Pingzhi Optics Bp850nm Bandpass Filter Made of Black Glass Material for Strong Light Suppression
Introduction to HWB850 Black Glass Products:
Black glass is a type of optical colored glass. The filter products with relatively high cut-off depth requirements are produced by utilizing the optical properties of black glass. It can cut off more deeply in the cut-off optical band and filter out more interfering light, thus achieving a relatively perfect cut-off degree between OD3 and OD6.
Technical parameters of the 850nm narrow-band filter made of black glass:
Center wavelength: 850±2nm
Incident angle: 0°
Half-peak bandwidth: 25nm
Peak transmittance: 90% (according to customer requirements)
Product size: 3mm - 80mm (customizable)
Cut-off wavelength: 200nm - 1100nm (according to customer requirements)
Cut-off depth: OD3 - OD6 UV - NIR
Product material: Black glass (HWB850)
Surface finish: National standard level 3, US military standard 60 - 40
