Semrock VersaChrome Tunable Bandpass Filters

VersaChrome Edge tunable fitlers unlock virtuallly unlimited spectral flexibility for fluorescence micrsocopy 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
