Bi850-55 | Bi850 Near-IR Interference Bandpass Filter
Part: Bi850-55
Diameter: M55 x P0.75
The MidOpt Bi850-55 is used in conjunction with common IR illuminators operating at or near the 850nm wavelength range. These filters feature a narrow-band design that is ideal when ambient lighting conditions create poor contrast. They are commonly used in security, traffic control, LPR, and industrial inspection applications. 850nm is also a very commonly referenced wavelength used in various vegetation health index calculations. Bi850 can be supplied as either mounted or unmounted filters and is available in 0.5 and 1.0mm thicknesses. All MidOpt filters can also be purchased unmounted or in custom dimensions upon request from Machine Vision Direct.
