VY Optoelectronics Co., Ltd.

IR-CUT Filter is the key part for digital mobile telephone with photographic lens, PC cameras,telephone with image etc. It's mainly is that the optical glass' surface will be done a coating with IR CUT, it only let the light-wave in stated scope to pass. Add the IR-CUT Filter between lens and CCD or CMOS image sensor, can effectively to repress the wave disturbance which cause by the pass of the light-wave whose frequency is higher than CCD or CMOS image sensor, and also it can repress infrared light-wave, then make the image more clearly and stability. Material: IR-CUT Filter is made of optical glass with the coating of IR-CUT on the surface, such as B270, D263T, BK7 ,IR-Glass(Blue-Glass)etc. Its shape can accord to the customer's special request to produce. Optical Characteristic:Flatness NR number:<= 3 Spectrum Characteristic: 400~620nm Tmin>85% 645 ± 10nm T=50% 740~1050nm Tmax<3% Tave<1% ( Can order to make according the customer request)
Filters are designed by their manufacturers to transmit or absorb different wavelengths of light. And they are widely used in scientific experiments and industrial applications where that change is necessary.
