Tuneable Edge Filters

Tuneable edge filter is a customised product. It usually belongs to 2-port optical tuneable filter product platform. Instead of using narrow bandpass filter in the 2-port tuneable optical filter, the tuneable edge filter utilises a low-pass or long-pass interference filter. By changing the incident angle of the light beam, the cut-off wavelength will be tuned. Standard Tuneable edge filters support C-band or L-band wavelength range.
In other applications, Tuneable edge filter can be in 3-port configuration, in which one output is long pass and the other one is low pass.
