These new, game-changing optical filters no 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. Versachrome filters combine the highly desirable spectral characteristics and two-dimensional imaging capability of thin-film optical filters with the wavelength tuning flexiblity of a diffraction grating.

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.

These filters are ideal for applications ranging from fluorescence imaging and measurements to hyperspectral imaging and high-throughput spectroscopy. And with high optical quality and damage threshold, they are well-suited for a wide range of laser applications as well.

Features:

  • Tuning range of greater than 11% of the normal-incidence wavelength
  • High transmission (>93% typical) over passband
  • Polarisation insensitive over full tuning range
  • Imaging optical quality - low scatter, wavefront distortion, and beam deviation
  • Hard-coating reliability and high laser damage threshold (1J/cm2)
  • Excellent out-of-band blocking
