The placement box 305 is fixedly connected to the left side of the front of the connecting frame 2. The placement plate 301 is fixedly connected to the front of the placement box 305. The limiting frame 302 is fixedly connected to the top front of the placement plate 301. The light guide plate 303 is fixedly connected to the top inner part of the limiting frame 302. The sealing plate 304 is fixedly connected to the side of the light guide plate 303. The high-precision grating test pattern plate 307 is fixedly connected to the bottom back of the placement plate 301. The placement plate 308 is connected to the connecting frame 2. On the inner right side of the mounting bracket 2, the outer frame plate 309 is connected to the front of the placement plate 308, and the high-precision grating test pattern plate 307 is connected to the front of the placement plate 308. There are two sets of brightness adjustment components 3, which are distributed in the upper left corner of the high-precision grating test pattern plate 307. The front of the placement box 305 is provided with a placement rectangular groove. The LED lamp 306 is fixedly connected to the inner two sides of the placement box 305. The inner area of ​​the outer frame plate 309 is adapted to the area of ​​the high-precision grating test pattern plate 307. The outer frame plate 309 can protect the high-precision grating test pattern plate 307, and the light source projects light evenly onto the high-precision grating test pattern plate 307 through the light guide plate, so that it can be used normally.

[0027] The stable placement component 4 includes a connecting frame plate 401, a connecting strip plate 402, a placement rectangular plate 403, and suction cups 404. The connecting frame plate 401 is fixedly connected to the bottom of the receiving base 1, the connecting strip plate 402 is fixedly connected to the inside of the connecting frame plate 401, the placement rectangular plate 403 is fixedly connected to the center inside the connecting frame plate 401, and the suction cups 404 are fixedly connected to the bottom of the placement rectangular plate 403.

The arrangement of multiple suction cups 404 can increase the contact area during fixation and ensure the stability of placement.

[0028] In use, the device can be placed using the stable placement component 4 at the bottom of the base 1. During placement, the suction cup 404 should be attached to the top of the mounting base, and then pressed down until the bottom of the connecting frame plate 401 also contacts the mounting base. The suction cup 404 is used for adsorption, but the connecting frame plate 401 also contacts the base to ensure stability. After placing the device, the brightness of the light source can be adjusted using the brightness adjustment component 3 to adapt to the testing requirements under different lighting conditions. Adjusting the brightness is achieved by controlling the opening of different numbers of LED lights 306.
