850nm Dual Bandpass Filter Visible + 850nm NIR

Multi Bandpass Filter

Description:

Precision ground and polished 850nm filters pass visible and 850nm LED or laser diode illumination. 850nm LEDs are perhaps the brightest of all infrared LEDs. Using a 850nm filter over (or behind) the camera lens allows for full color imaging by day and excellent monochrome contrast at night. These filters are useful for machine vision, 3D point cloud imaging and day/night camera surveillance applications. “M25.4” or custom cut 1.0 or 0.5mm thick 850nm filters with standard 10-5 or better surface quality are most typically mounted between the camera lens and the sensor.
