Infrared narrow band filter
Buy it now
Infrared narrow-band filters allow light signals to pass through in a specific wavelength band, while blocking light signals on both sides that deviate from this band. The passband of a narrow-band filter is relatively narrow, generally less than 5% of the central wavelength value.
MFrontier The narrowband filter developed uses substrate materials such as monocrystalline silicon, sapphire, germanium, calcium fluoride, zinc selenide, etc., covering Φ 150 * 0.5mm, Φ 100 * 0.5mm, Φ 76 * 0.5mm, Φ Sizes such as 25 * 0.6mm can be customized as needed.
Its main parameters include: center wavelength λ 0. Half bandwidth (FWHM), peak transmittance Tmax, cutoff range, cutoff depth (OD value).
