Tunable Bandpass Filters
With VersaChrome optical bandpass filters from Semrock, the spectral characteristics of the optical filter can be flexibly tuned by changing the angle of incidence. It is possible to tune over a very wide wavelength range while essentially maintaining the spectral performance of the filter. VersaChrome filters thus combine the spectral properties and two-dimensional imaging performance of a thin-film filter with the flexibility of an optical grating (diffraction grating).
