Tunable Bandpass Filters support variety of tuning ranges.

Press Release Summary:




By adjusting angle of incidence, Tunable Bandpass Filters offer tunability over broad wavelength range with essentially no change in spectral performance. Tuning range is greater than 12% of normal-incidence wavelength. Filters are suited for applications ranging from fluorescence imaging and measurements to hyperspectral imaging and high-throughput spectroscopy. With polarization insensitivity and high damage threshold, units are also suitable for laser applications.

o Variety of Broad Tuning Ranges Available

o Ultra-low Polarization Sensitivity

These Tunable Bandpass Filters do what no thin-film filter has ever done before: offer wavelength tunability over a broad wavelength range simply by adjusting the angle of incidence. The patent-pending design offers essentially no change in spectral performance over the entire tuning range. Thus, these filters combine the desirable spectral characteristics and imaging capability of thin-film optical filters with the wavelength tuning flexibility of a diffraction grating.

Tunable Bandpass Filters 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.
