IR Cut-Filters
 |
Infrared (IR) cut-off filters are used with color CCD or CMOS imagers to produce true color images. An IR cut-off filter blocks the transmission of the infrared while passing the visible. This can be done with two optical techniques: absorption or reflection. Absorptive filters are made with special optical glass that absorbs near infrared radiation. Reflection type filters are essentially short-pass interference filters that reflect infrared light with high efficiency. We offer two types of absorptive filters: IRC20 and IRC21. The standard reflection type (IRC30) filter offers cut-off wavelength at 645nm (+/-7nm). Other cut-off wavelength can be selected for custom orders. IRC20 type is recommended for CCD imagers while IRC21 and IRC30 are more suited for CMOS imagers. |
