Detailed Description

Optical Infrared (IR) cut-off filters are used with color CCD/CMOS imagers to produce color images. An IR cut-off filter blocks the transmission of the infrared while passing the visible light, which will increase the image quality and the true colour. IR cut-off filters are mainly applied to CCD/CMOS Imaging System, such as Mobile camera, digital camera, PC camera, CCTV　camera, Visual phone and Video door phone etc. Substrate--------------------D263T/B270/BK7 Round type size-------------φ3.6~φ30 mm (±0.05 mm) Thickness--------------------0.3mm, 0.4mm, 0.55mm, 0.7mm, 1.1mm Surface Quality--------------40/20, 60/40 IR Coating--------------------T50% = 640/645/650/660nm±10 nm 400~420 nm-----------------Tmin.≥85% 420~620 nm-----------------Tmin≥88%, Tave≥90% 650±10nm---------------------T=50% 700~1000 nm----------------Tmax≤2%, Tave<1% 1000~1100 nm---------------Tmax≤4% (The final detailed specifications are customized or suggested by Lenoptec. ) Products Include: ·Acrylic Filter ·Dichroic Filter ·Beam Splitter ·Reflective Coating ·Interference Filter ·Waterproof and dustproof coating ·AR coating ·UV-IR Blocker ·IR Cut-off Filter
