Semrock VersaChrome Tunable Bandpass Filters

VersaChrome Edge tunable filters unlock virtually unlimited spectral flexibility for fluorescence microscopy and hyperspectral imaging, as well as for spectroscopy applications. By utilising a combination of VersaChrome Edge tunable long-wave-pass and short-wave-pass filters, a bandpass filter as narrow as sub 5nm FWHM or as wide as 12% of the centre wavelength throughout the visible and near-infrared wavelength ranges can be created. Semrock's patented tunable thin-film filters can't be found anywhere else in the market.

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

As the industry’s best for high-performance optical filters, Semrock products from IDEX Health & Science deliver the stability required for life science, analytical, and medical diagnostic instrumentation. By utilising proprietary hard-sputtered coatings, our filters eliminate environmental degradation and drift—a level of reliability backed by our 10-year warranty. We ensure faster measurements and minimal downtime by prioritising steep edges and deep blocking to maximise your signal-to-noise ratios. From standard components to custom solutions, Semrock filters provide the superior stability and spectral precision necessary to optimise the most demanding optical systems.
