910nm optical filter

Precision narrow bandpass interference filter centered at 910 nm (near-infrared), designed to transmit a sharp 910 nm ± band while blocking visible light and out-of-band NIR.

Hard-coated via ion-assisted deposition on optical glass with steep edges and deep out-of-band blocking. The 910 nm wavelength is completely invisible to the human eye, making it ideal for covert night vision, IR illumination isolation, and industrial sensing.

Fully customizable in diameter (22mm, 36mm, 39mm, or any custom size) and bandwidth for OEM integration.
