Bandpass Filters

Bandpass filters are optical elements that are designed to transmit a specific spectral band with high efficiency, while reject others. The characteristics of the bandpass are controlled by multilayer dielectric coatings

Substrate: commercial quality window or precision window. Please refer to the optical window page.

Typical Transmission samples:

Long wave pass (LWP) filter coating T<1%@200-570nm & T>90%@630-1100nm, AOI=0deg.

Short wave pass (SWP) filter coating Tavg<1%@750-1100nm & Tavg>90%@400-680nm, AOI=0deg.

Bandpass filter T>90%@640-705nm, Block others, AOI=0deg.
