Description

Technical Field

[0001] The utility model relates to the technical field of polarized glass testing, in particular to a polarized glass measuring object rack and a polarized glass measuring device. Background Art

[0002] Polarized glass is a type of optical material with light polarization effect, which is widely used in optoelectronic devices such as optical isolators, optical modulators and lasers. For the preparation of this type of material, the current mainstream preparation method in the industry is the stretching reduction method. By stretching and reducing the glass containing silver halide or copper halide crystals, the glass can obtain an internal high aspect ratio array nanosilver / copper structure. The outer electrons of the highly oriented nanosilver / copper single substance in the glass oscillate under the electromagnetic field of the incident light wave and the electron Coulomb force. When the wavelength of the incident light is at the same frequency as the oscillation, the particles absorb the light, and the long axis and short axis of the particles absorb the light differently. It can be seen from Mie theory and C++ simulation calculations that when the aspect ratio of the nanosilver particles in the glass is larger, the light absorption band moves toward the infrared.

[0003] When using an infrared polarizing microscope to perform microscopic observation of the thickness of the polarization layer of a sample, since the polarization direction of the microscope is fixed, in order to obtain a better observation field of view, the sample stage is often rotated to obtain an extinction angle parallel to the polarization direction of the microscope. When the sample is rotated, a slight deviation in the polarization angle often affects the clarity of the light and dark boundaries of the observation area; and since the thickness of current conventional near-infrared polarizing glass is between 0.12 and 0.2 mm, when the sample thickness surface is placed on a transparent stage such as a slide and rotated, the small contact surface between the sample and the stage may cause a risk of the sample tipping over during the rotation process, and the small thickness surface of the sample cannot stand stably on the stage.

[0004] At the same time, when observing multiple samples, frequent replacement of the stage reduces the test efficiency. Therefore, the industry urgently needs to develop a device for observing the polarization layer thickness of infrared polarized glass that is easy to operate, has an adjustable micro-polarization angle, and is high-definition, and it is also urgent to develop a transparent stage that is suitable for the observation of small-sized samples and is anti-dumping, stable, and efficient.

[0006] To achieve the above-mentioned purpose, on the one hand, the utility model provides a polarization glass measurement carrier, comprising: a light-transmitting base, on which a plurality of sample slots arranged at intervals are arranged, for accommodating the polarization glass to be measured and embedding and placing it from the thickness surface; a plurality of groups of double-sided parallel rods, each group of the double-sided parallel rods comprising single-sided parallel rods established on both sides of the width of the sample slot, the single-sided parallel rods are fixed to the light-transmitting base and extend out top rods respectively, for contacting the two side surfaces of the polarization glass for limiting; a plurality of spacing adjustment mechanisms, respectively connected to a corresponding group of the double-sided parallel rods, for adjusting the relative positions of the double-sided parallel rods and the corresponding sample slots.

[0007] In one embodiment of the present invention, the light-transmitting base is provided with a concave area for accommodating the movement of the double-sided parallel rods.

[0010] On the other hand, the utility model also provides a polarization glass measuring device, comprising: a polarization glass measuring carrier as described in any one of the above embodiments; and a multi-space mobile platform, wherein the polarization glass measuring carrier is arranged on the multi-space mobile platform and can be driven by the multi-space mobile platform to move in three mutually perpendicular directions of X, Y, and Z.

[0011] In one embodiment of the utility model, the multi-space mobile platform includes two layers of movable plates, which move in the X direction and the Y direction respectively. The multi-space mobile platform is also connected to a screw support frame, and moves in the Z direction through the screw support frame.

[0012] In an embodiment of the present invention, light holes are arranged at corresponding positions on the upper and lower movable plates, and scale lines extending in the X direction and the Y direction are arranged with the light holes as the origin.

[0013] In one embodiment of the utility model, the polarized glass measuring device also includes: a light source for emitting test light; a polarizing assembly, including a polarizer and a rotating motor for driving the polarizer to rotate, wherein the polarizer can adjust the polarization angle of the test light by rotating; an imaging system, including a multi-power objective lens, for imaging the test light passing through the polarized glass to obtain a boundary field of view of the polarization layer thickness of the polarized glass.

[0014] In one embodiment of the utility model, the polarization glass measuring device further includes: a host computer connected to the rotary motor and the multi-power objective lens, used to control the rotary motor to rotate at a preset step angle and display the image formed by the multi-power objective lens.

[0015] In one embodiment of the utility model, the polarizing assembly further comprises: a rotating frame for carrying the polarizer, the rotating frame is provided with a rotation scale of 0° to 360°, and the rotating motor drives the polarizer to rotate within the range of 0° to 360° through the rotating frame.

[0031] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0032] The terms "first", "second", "third", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0033] like Figure 1 , 2 As shown in Figures 3 and 4, an embodiment of the utility model provides a polarized glass measurement carrier, comprising: a light-transmitting base 20, a plurality of sample slots 21 arranged at intervals on the light-transmitting base 20, parallel rods 22, and a parallel rod spacing adjustment mechanism 24. The sample slots 21 are used to accommodate the polarized glass to be measured and embedded and placed from the thickness surface. The parallel rods 22 include a plurality of groups of double-sided parallel rods, each group of double-sided parallel rods includes single-sided parallel rods set on both sides of the width of the sample slots 21, the single-sided parallel rods are fixed to the light-transmitting base 20, and top rods 23 are extended respectively, which are used to contact the two side surfaces of the polarized glass for limiting. The double-sided parallel rods are connected to the spacing adjustment mechanism 24, which is used to adjust the relative positions of the double-sided parallel rods and the corresponding sample slots 21, so that the polarized glass is stably fixed.

[0034] Furthermore, the polarized glass measuring carrier is made of visible-infrared transparent material, for example, a concave area for the movement of the parallel rod 22 is provided to accommodate the movement of the double-sided parallel rods. For example, the distance a between the left and right concave support feet of the concave area of ​​the transparent base 20 is 40 mm, the concave depth b is 0.6 mm, the parallel rod diameter r is 0.5 mm, the concave depth b>parallel rod diameter r, and (concave depth b+sample slot depth c)<transparent base thickness f=3 mm, which can prevent the parallel rod movement process from affecting the polarized glass stably placed in the sample slot 21.

[0035] Furthermore, a plurality of sample slots 21 are provided on the long side of the transparent base 20, and numbers 25 are provided on the upper side of the substrate corresponding to the sample slots 21 to facilitate the distinction when observing multiple samples. For example, the width of the sample slot 21 is g = 0.4 mm, the depth is c = 0.5 mm, the width of the sample slot g is greater than the thickness d of the polarizing glass, the depth of the sample slot c is less than the width h of the polarizing glass, and the length of the polarizing glass L is less than the length of the sample slot k = 12 mm < the width of the transparent base j = 25 mm, which can ensure that the polarizing glass is placed in the sample slot from the thickness surface and partially exceeds the sample slot for positioning.

[0036] Furthermore, the parallel rods 22 and the top rod 23 are made of transparent polymer materials, and the parallel rods on both sides are connected to the spacing adjustment mechanism 24. The spacing adjustment mechanism 24 moves the relative positions of the parallel rods 22 on both sides of the sample slot 21 by adjusting the knob; the minimum adjustable step of the spacing adjustment knob is 0.1 mm.

[0037] In addition, if Figure 4 As shown, the embodiment of the utility model also provides a polarization glass measuring device, for example, including the above-mentioned polarization glass measuring carrier and a multi-space mobile platform. The polarization glass measuring carrier is arranged on the multi-space mobile platform and can be driven by the multi-space mobile platform to move in three mutually perpendicular directions of X, Y, and Z.

[0038] Furthermore, the multi-space mobile platform includes two layers of movable plates, and moves in the X direction and the Y direction respectively through the upper and lower layers of movable plates. The multi-space mobile platform is also connected to a screw support frame, and moves in the Z direction through the screw support frame.

[0039] In particular, a light-transmitting square hole 6 with a side length of 10 mm is provided in the middle of the upper and lower movable plates; the edges of the X and Y movable plates of the multi-space movable sample stage take the center of the light-transmitting square hole as the origin, and symmetrically extend scale lines with a total length of 100 mm to the front, back, left and right of the origin; the multiple magnifications of the multi-magnification objective lens are 5, 10, and 20 respectively.

[0040] Optionally, the polarized glass measuring device further includes, for example, a base, an infrared or visible light source system, a motor-driven rotatable polarizer system, an imaging system and a host computer.

[0041] The rotatable polarizer system 3 includes a rotating motor 17 and a polarizer 16 integrally connected to a rotating frame with a scale 15. The rotation of the polarizer is driven by a stepper motor 17 controlled by an external host computer 13. In particular, the minimum rotation angle of the polarizer system 3 is 0.01°. The rotatable polarizer 16 is a birefringent crystal. The rotating polarizer system 3 can adjust the polarization angle of the output light to 0° to 360°.

[0042] The following further illustrates a method for measuring the thickness of the reduction layer of polarized glass using the measuring device proposed in this embodiment:

[0043] like Figure 6 , Figure 7 As shown, for example, a test piece 19 having a width h of 2 mm, a length L of 6 mm, and a thickness d of 0.2 mm is cut out along the stretching direction of the stretching base material 18 .

[0044] like Figure 1 , 23, the piece to be tested 19 is stood up with its thickness surface and placed in the upper groove 21 on the transparent base 20, and the push rods 23 integrally connected to the parallel bars 24 on both sides of the upper groove 21 are made to contact the upper surface of the glass 19 to be tested and protrude from the upper groove 21 by rotating the parallel bar spacing adjustment knobs 24, and the push rods 23 on both sides of the upper groove 21 are made to contact the upper surface of the glass 19 to be tested and protrude from the upper groove 21, and the push rods 24 are continued to be tightened to make the side piece 19 straight and stable without shaking; the sample rack 20 carrying the piece to be tested 19 is placed across the two sides of the light-through hole 6 on the sample stages 4 and 5.

[0045] like Figure 4 As shown, turn on the light source 2 of the reduction layer thickness measuring device, adjust the objective lens magnification of the measuring device from 11 to 5 times, find the boundary field of the sample to be measured by adjusting the sample stage X, Y axis position control knob 7 and the sample stage Z axis position control knob 8, further magnify the objective lens magnification from 11 to 10 times, and fine-tune the multi-space sample X, Y, Z position controllers 7 and 8 to obtain a clearer boundary field of polarized glass thickness.

[0046] The upper computer 13 program controls the motor 17 to rotate the rotating frame 15 carrying the polarizer 16. First, the polarization angle of the incident light is adjusted by 1° step rotation. After rotating to a certain range, the glass thickness picture of the light and dark transition is observed, and then the rotation step is reduced to 0.01° until the upper computer 13 displays a clearer light and dark transition image. Finally, a line is drawn to measure the overall thickness of the dark area.

[0047] Figure 8 The thickness of the reduction layer of the polarizing glass measured by the above method, the thickness of the dark areas on both sides of the polarizing glass thickness are 41 and 39 um respectively; when there are multiple samples to be measured, after the test of the previous sample is completed, move the X, Y axis controller 7 to expose the next sample to the light hole 6, repeat the above steps, and the batch test of the thickness of the reduction layer of the polarizing glass can be completed.

[0048] In summary, the polarization glass measuring carrier and polarization glass measuring device proposed in the embodiment of the utility model can limit the polarization glass to be measured by setting sample slots and corresponding parallel rods and push rods, so that the polarization glass to be measured can be placed stably on the transparent carrier, ensuring that the thickness surface of the small-size sample is strictly perpendicular to the light path direction, and the designed multi-sample slot structure solves the problem of multiple pick-up and placement, thereby improving the test efficiency; by designing an electric polarizer with adjustable micro-polarization angle, the problem of fixed polarization direction of the current infrared microscope is solved, and by driving the rotating polarizer by a motor, a higher polarization angle stepping accuracy can be achieved, thereby improving the clarity of the polarization glass thickness microscopic observation area; the polarization glass measuring carrier is provided with scale lines in the X and Y directions, which can accurately move the position of the sample to be measured, facilitate observation of the restoration of different areas of the sample, and make the polarization glass measuring device have the advantages of simple operation, fast timeliness, low cost and low error.
