When adjusting the dimming glass, the area is divided directly with a single dimming block as a unit, and then the controller controls several single dimming blocks to be transparent or matte to achieve the control of the target pattern; The dimming block can be controlled by the controller to achieve light transmission in the target detection area and matte outside the target area. Then, the first mounting frame on the side wall of the glass workbench can be driven to move by adjusting the lead screw to move, so that the position of the glass workbench can be moved in the X-axis and Y-axis directions, and the material can be adjusted to move to the center of the target area, which greatly reduces the interference effect of light in the non-detection area on the detection area, which is conducive to improving the accuracy of irradiation measurement and improving the measurement accuracy. A first mounting frame 609 is fixedly mounted on two adjacent side walls of the glass workbench 5, a Y-axial slide groove 17 is mounted on one side wall of the base 8 below the first mounting frame 609, and an X-axial slide groove 18 is mounted on the other side wall, and a slider 605 is slidably connected inside the X-axial slide groove 18 and the Y-axial slide groove 17, a connecting plate 19 with at least one pair of first bearing seats 603 is arranged on the top of the slider 605, a screw rod 607 with a nut 608 is rotatably mounted between the two first bearing seats 603, and the first mounting frame 609 is fixedly connected to the nut 608; In addition, the interior of the X-axis slide groove and the Y-axis slide groove are connected to the connecting plate through sliders, which also improves the stability of the glass workbench during movement, reduces the shaking of the glass workbench during movement, and improves the position accuracy of the material placed on the glass workbench, thereby improving the overall detection accuracy.

[0031] A strip through hole 108 is provided on the top of the side shell 109, and a reciprocating slide rail 110 having an electric slider 605 is provided inside the side shell 109. A probe 107 electrically connected to an ion generator 113 is installed on the top of the electric slider 605. The probe 107 that can extend through the strip through hole 108 is located between the dimming glass 2 and the air outlets of the upper air outlet pipe 141 and the lower air outlet pipe 142. During the use of dimming glass, its bottom and top may be affected by static electricity, causing dust to adhere. The accumulation of dust may affect the light transmittance of the dimming glass. During the operation of the flash tester, the probe reciprocates along the reciprocating slide rail through the electric slider and emits ions upward. Then, the blower is started, and the upper and lower air outlet ducts are switched regularly through the conversion switch, thereby driving ions to be intermittently sprayed to the upper and lower ends of the dimming glass, thereby cleaning both sides of the dimming glass, effectively removing dust accumulation and ensuring its light transmittance.

[0032] A valve 105 is installed on each of the upper air outlet pipe 141 and the lower air outlet pipe 142 , and both valves 105 are electrically connected to the conversion switch 103 .

[0033] A second bearing seat 604 is arranged at the top of the above-mentioned connecting plate 19 parallel to the first bearing seat 603, and a sliding rod 602 is fixedly installed between the two second bearing seats 604 and is connected to a limiting slider 605 that slides toward the outer wall.

[0038] The dimming glass 2 and the controller 10 are electrically connected via a first wire 11 .

[0039] The controller 10 is electrically connected to a processor 9 .

[0040] The working principle is: When in use, since the dimming glass is composed of an array of dimming blocks, when the area is locked on the computer, according to the set parameters, the controller controls the dimming blocks to form a minimum area that can contain the locked area to be in a light-transmitting state, and the rest of the positions are in a matte state, reducing the light transmittance and blurring the lines at the blocked positions. Therefore, when the camera is measuring, the amount of lines included in the measurement is reduced, thereby reducing the possibility of obstruction caused by the remaining lines, and ensuring the accuracy of the partition measurement of fine parts; The dimming glass color display area is realized by the dimming block according to the dimming block position required by the locked area to achieve the dimming state of the area. When adjusting the dimming glass, the area is divided directly with a single dimming block as a unit, and then the controller controls several single dimming blocks to be transparent or matte to achieve the control of the target pattern; When the range of flash measurement is limited by dimming glass, the glass workbench is adjusted synchronously according to the area lock on the computer. Through the Y-axis slide groove and the X-axis slide groove located on the adjacent two sides, the lead screw is driven to rotate by the servo motor, thereby driving the glass workbench to move in two directions under the action of the nut, so that the edge of the area set on the computer can coincide with the boundary position of the dimming block on the dimming glass, thereby achieving more subtle adjustments and achieving complete locking of the set area; In addition, during the use of dimming glass, its bottom and top may be affected by static electricity, causing dust to adhere. The accumulation of dust may affect the light transmittance of the dimming glass. During the operation of the flash tester, the probe reciprocates along the reciprocating slide rail through the electric slider and emits ions upward. Then, the blower is started, and the upper and lower air outlet ducts are switched regularly through the conversion switch, thereby driving ions to be intermittently sprayed to the upper and lower ends of the dimming glass, thereby cleaning both sides of the dimming glass, effectively removing dust accumulation, and ensuring its light transmittance.

[0041] When the above-mentioned universal flash tester is used, the dimming block can be controlled by the controller to achieve light transmission in the target detection area and matte outside the target area. Then, the first mounting frame on the side wall of the glass workbench is driven to move by adjusting the lead screw to realize the position movement of the glass workbench in the X-axis and Y-axis directions, and the material is adjusted to move to the center of the target area, which greatly reduces the interference effect of light in the non-detection area on the detection area, which is conducive to improving the accuracy of irradiation measurement and improving the measurement accuracy. In addition, the interior of the X-axis slide and the Y-axis slide are connected to the connecting plate through the slider, which also improves the stability of the glass workbench during movement, reduces the shaking of the glass workbench during movement, and improves the position accuracy of the material placed on the glass workbench, thereby improving the overall detection accuracy; In addition, when the blower is working, the airflow containing ions can be blown toward the dimming glass through the upper and lower air outlet ducts to the probe, which greatly reduces the adsorption effect of static electricity, is conducive to the separation of dust, greatly reduces the adhesion and accumulation of dust, improves the cleaning effect, and ensures the accuracy of measurement.
