Description

Tunable Bandpass Filter VersaChrome

These game-changing optical filters do what no thin-film filter has ever done before: offer wavelength tunability over a very wide range of wavelengths by adjusting the angle of incidence with essentially no change in spectral performance. The tunable bandpass filter VersaChrome combines the highly desirable spectral characteristics and two-dimensional imaging capability of thin-film optical filters with the wavelength tuning flexibility of a diffraction grating. They are so innovative, they are patent pending.

With a tuning range of greater than 11 % of the normal-incidence wavelength (by varying the angle of incidence from 0 to 60°), only five filters are needed to cover the full visible spectrum. They are ideal for applications ranging from fluorescence imaging and measurements to hyperspectral imaging and high-throughput spectroscopy. With their excellent polarization insensitivity and high optical quality and damage threshold, they are well-suited for a wide range of laser applications as well.
