Product Description
Product Description

 

Optolong Infrared filters, sometimes called IR filters or heat-absorbing filters, are designed to allow IR mid-infrared wavelengths while block visible light.    They are often used in devices with bright incandescent light bulbs (such as slide and overhead projectors) to prevent unwanted heating.
There are also filters which are used in solid state (CCD or CMOS) video cameras to allow IR due to the high sensitivity of many camera sensors to near-infrared light.

Digital cameras are usually equipped with IR-blocking filters to prevent unnatural-looking images.    IR-transmitting (passing) filters, or removal of factory IR-blocking filters, are commonly used in infrared photography to pass infrared light and block visible and ultraviolet light.    Such filters appear black to the eye, but are transparent when viewed with an IR sensitive device.
