IR-Sperrfilter

IR-CUT Filtr: The IR-CUT Filter which also called Infrared filter is normally used in solid state (CCD or CMOS) video cameras to reflect or block IR wavelength while passing the visable light. It can be used on digital mobile telephone, CCTV (Surveillance cameras), PC cameras, videophone etc. The IR-CUT Filter is basically a high quality optical glass substrate which had a IR-CUT coating on its surface. It could effectively repress the wave disturbance which caused by the light of near-infrared light, to make the image clearly and steady.Substrate D263T/B270/BK7/Floatglass Size 3.6 30mm Thickness 0.1mm, 0.3mm, 0.4mm, 0.5mm 0.7mm, 1.1mm Surface 40/20, 60/40 IR Coating T50% T50%=640/645/650/660nm+/-10nm 400 420nm Tmin.≥85% 420 620nm Tmin.≥88%, Tave.≥90% 650±10nm T=50% 700 1000nm Tmax. ≤2%, Tave<1% 1000 1100nm Tmax≤4%
