Specific implementation mode
The utility model is further described with reference to specific embodiment and attached drawing.
As shown, a kind of screening tooling of optical filter of the utility model, including light source receiving device 1, for placing filter
There is angle adjusting face 101, the angle adjusting face 101 to be equipped with for the loading disk 3 of mating plate, 1 top of the light source receiving device
The light path hole 102 of the light source receiving device 1 is penetrated through, the light path hole 102 includes being connect from angle adjusting face 101 to the light source
Receiving apparatus 1 extends internally and angle with horizontal plane is the tilting section 112 of α, the vertical section that is connected with the tilting section 112
122,1 lower removable of the light source receiving device is provided with sliding block 4, and there is through-hole, the loading disk 3 to position on the sliding block 4
In on the through-hole, and the vertical section 122 intersects vertically with the optical filter in the loading disk 3.
Specifically, the loading disk 3 can be integrally formed setting with the sliding block 4, the loading disk 3 can in the production process
It is directly arranged on the sliding block 4 using plastic material, while may be alternatively provided as removably loading disk 3.
Specifically, test philosophy is as follows：One is placed on without the same type detector of optical filter on testing cassete, is made
It works always, then uses a stable light source to irradiate detector, so that detector is converted optical signals to electric signal and show
On oscillograph, responsiveness parameter E can be measured on oscillograph, then by optical filter be placed on signal source and detector it
Between, parameter E1 at this time is read, because optical filter has signal certain attenuation, therefore E1≤E, then replaces and filters successively
Built-in testing goes out parameter E11, E12, E13..., finally analyzes data, carries out grade classification according to parameter size, obtains knot
Fruit.
Specifically, 101 angle with horizontal plane of the angle adjusting face is θ, the sum of the angle α and angle theta are 90 °,
In the case of light source different incidence angles, the test parameter of optical filter can be varied from, therefore ensure accurate test data, just
Meet the data demand of signal source incidence angles degree parameter, incident angle may be configured as 0 °, 10 °, 20 °, 30 ° etc..
