Screw in low profile IR-CUT filter for CS and C-mount cameras

Kurokesu screw-in optical filters are designed for CS and C-mount lenses, providing a simple way to control the camera’s spectral response without modifying the lens mount or the camera body. They use a low profile 19×1mm glass element with low profile Aluminum frame that threads directly into the camera body. 

Two spectral options are available. The IR-cut (visible-pass) version transmits the 400-650nm visible range while blocking infrared, ensuring accurate color reproduction under daylight or artificial lighting. The NIR long-pass version blocks the visible spectrum and transmits near-infrared wavelengths above ~850 nm, enabling IR-only imaging for night vision, low-light inspection or machine-vision tasks that require controlled illumination. These screw-in filters offer a quick, mechanical way to switch between visible and IR-only operation and are compatible with most CS/C-mount lenses.

Filter size: CS-mount
