Product Details

The long wave pass filter has a transmission band of 500-2500 and a cutoff band of 200-665nm

Band selective absorption filter

The long wave pass filter is made of special colored glass. The dopants in the material absorb the spectrum of a specific band and pass through the long wave band. This kind of filter is absorption type and is not suitable for laser.

TJ: in this band, t = 50% t λ 0

λ 0: in the band above this wavelength, the transmittance reaches the required value t λ 0

 T λ 0: required value of transmittance in transmission band

 Cut off bandwidth (nm): the wavelength width when the transmittance increases from 10% t λ 0 to 80% t λ 0
