Infrared filter

Infrared filterS

The optical infrared filter filters out the visible spectrum, and the transmission wavelength is greater than the infrared radiation of about 750 nm.

Transmission characteristics of infrared filter

Features of infrared filter:

The transmittance of 850nm~2000nm infrared band is about 90%

780nm wavelength transmittance: 50%

Visible spectral transmittance with wavelength<740nm: 0%

Optional anti glare coating to reduce front surface reflection
