Description

Technical Field

[0001] The utility model relates to the technical field of polarized light analyzer devices, in particular to an integrated polarized light analyzer inserting piece group. Background Art

[0002] A polarizing analyzer is usually installed in the microscope. A polarizing analyzer is provided with a polarizer. When natural light passes through the polarizer, only light with the same polarization direction as that of the polarizer passes through, and polarized light in other directions is filtered out. This is used to identify whether a substance is singly refracting or birefringent.

[0003] The shell of a common polarizer in technology usually includes an upper shell and a lower shell connected up and down. Due to the material or the black dyeing process, the appearance color of the upper shell and the lower shell may have color difference, resulting in inconsistent colors of the entire upper shell and the lower shell. In addition, the upper shell and the lower shell are provided with grooves. Due to processing errors, the upper and lower grooves may not be aligned. Finally, the thickness of the polarizer is relatively thin, generally 6mm. Usually, the thickness of the upper shell and the lower shell are 3mm respectively. The upper shell and the lower shell need to be provided with installation grooves for installing the polarizer respectively. The processing efficiency is low and the upper shell and the lower shell are prone to deformation during the processing, resulting in the total thickness after assembly not meeting the requirements, resulting in the polarizer being unable to be inserted into the microscope.

DETAILED DESCRIPTION

[0024] Combine the following Figure 1-5 The utility model is described in detail.

[0025] Figure 1The exploded view of the polarizing analyzer blade set in the prior art is shown, and it can be seen that the outer shell adopts a blade seat 10' and a cover plate 20' connected up and down, which may easily lead to inconsistent colors of the blade seat 10' and the cover plate 20'. In addition, the outer surfaces of the blade seat 10' and the cover plate 20' are provided with grooves 103'. Due to processing errors, the upper and lower grooves 103' may not be aligned. Finally, the thickness of the analyzer is relatively thin, generally 6mm, and the thickness of the blade seat and the cover plate is usually 3mm respectively. The blade seat 10' and the cover plate 20' need to be respectively provided with mounting grooves for installing the analyzer. The processing efficiency is low and the blade seat and the cover plate are easily deformed during the processing, resulting in the total thickness after assembly not meeting the requirements, and the analyzer cannot be inserted into the microscope.

[0026] The utility model proposes an integrated polarizing analyzer insert set, including an insert seat 10 and a cover plate 20. The insert seat 10 is provided with an installation cavity with an opening at one end, and an analyzer device is provided in the installation cavity.

[0027] Therefore, different from the upper and lower layered form commonly used in the prior art, the cover plate 20 is completely located inside the socket sheet, so that the plug-in group appears to be integral in appearance, and the grooves 103 can be all set on the outer surfaces of both sides of the plug-in seat 10, avoiding the misalignment that may occur when the grooves 103 are set on the plug-in seat 10 and the cover plate 20 respectively, and solving the problem of color difference in appearance when the plug-in seat 10 and the cover plate 20 are connected to each other. In addition, since the cover plate 20 is completely located inside the plug-in seat 10, the thickness of the plug-in group depends on the thickness of the bottom of the plug-in seat 10, the deformation error caused by processing becomes smaller, the processing difficulty is reduced, and the dimensional accuracy is improved.

Further, the radial dimension of the toothed portion is greater than the radial dimension of the light exit hole 101 and the light inlet hole 201, so as to prevent the polarization unit 50 from being separated from the insert seat 10 from the light exit hole 101 or the light inlet hole 201.

[0029] In this embodiment, the insert seat 10 is provided with a first mounting groove 105, a second mounting groove 106 and a third mounting groove 107 for mounting the first gear portion 30, the second gear portion 40 and the polarization portion 50 respectively, and the first gear portion 30, the second gear portion 40 and the polarization portion 50 are not higher than the first mounting groove 105, the second mounting groove 106 and the third mounting groove 107 respectively.
