BP850-25.5 | BP850 Near-IR Bandpass Filter
Part: BP850-25.5
Diameter: M25.5 x P0.5
The MidOpt BP850-25.5 is recommended for high-power 830-850nm LED or laser diode lighting to improve contrast in surveillance applications or for infrared inspection. This filter features high peak transmission and particularly durable, robust coatings. This filter’s coated surface also greatly inhibits staining, unlike uncoated infrared filters, which are affected by year-round issues with heat, humidity, and/or air quality. All MidOpt filters can also be purchased unmounted or in custom dimensions upon request from Machine Vision Direct.
