Description

MidOpt DB850-40.5 Visible and 850nm NIR Dual Bandpass Filter

Precision ground and polished DB850 filters pass visible and 850nm LED or laser diode illumination. 850nm LEDs are the brightest of all infrared LEDs. Using a DB850 filter over (or behind) the camera lens allows 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 DB850 filters with standard 10-5 or better surface quality are typically mounted between the camera lens and the sensor.
