home bedrooms Single Perspective Tester

Brief Introduction:

One-way perspective curtains are special curtains with high reflectivity for visible light. They are usually used in home bedrooms, toilets, large  conference rooms and other places where privacy is required.
When the outdoor is bright than the indoor, the one-way perspective curtains can let the outdoor not see the indoor scene, but the room can see the outdoor scenery, its clarity depends on the intensity of outdoor illumination.
One way perspective testing device uses the illumination difference inside and outside of the test box to simulate the indoor lighting and sunlight on both sides of the window to test the performance of the one-way perspective fabric.
 
In the test, the standard vision chart is put into the test box, and the top incandescent lamp is adjusted so as to achieve the specified illumination of the surface;
The sample is suspended at the opening of the test box to adjust the brightness of the lateral projection light, and When the observer is unable to recognize the visual acuity values from the outside, the lowest illumination is the value of the sample.
The lower the results , the better the anti-glare properties of the material.
