[0018] This specific embodiment discloses a tool for measuring lens transmittance, such as Figure 1 and Figure 2 As shown, the base 1 includes a bottom plate 11, and an upwardly protruding main body 12 is provided on the bottom plate 11. Two side walls of the main body 12 are respectively provided with two screw holes.

[0019] The base 1 is provided with a first bracket 2 and a second bracket 3, which are parallel to each other and both of which are rectangular structures. The first bracket 2 is provided with an aperture 4, and the second bracket 3 is provided with a lens placement area 5 at a position opposite to the aperture 4. Figure 1 As shown, the lens placement area 5 is a U-shaped groove for placing the lens 8 to be measured. In addition, the lens placement area 5 can also be set to other shapes for placing the lens 8.

[0020] like Figure 2As shown, two first screw holes 22 are provided at the bottom of the first bracket 2. Figure 1 As shown, two second screw holes 32 are provided at the bottom of the second bracket 3. Figure 3 As shown, the first bracket 2 is connected to a screw hole on one side wall of the main body 12 through a first screw hole 22 and a first screw 23, and the second bracket 3 is connected to a screw hole on the other side wall of the main body 12 through a second screw hole 32 and a second screw 33. Figure 3 As shown, an integrating sphere 6 is provided outside the second bracket 3 .

[0021] The tooling fixture also includes a positioning rod 7. Figure 2 As shown, the first bracket 2 is provided with a first positioning hole 21.
