887 nm VersaChrome Edge™ tunable longpass filter

Semrock Logo

VersaChrome filters do what no thin-film filter has done before – offer tunability over a very wide range of wavelengths by adjusting the angle of incidence with essentially no change in spectral performance. They combine the spectral characteristics and two-dimensional imaging performance of a thin-film filter with the wavelength-tuning flexibility of a diffraction grating.

VersaChrome Edge tunable filters unlock virtually unlimited spectral flexibility for fluorescence microscopy and hyperspectral imaging, as well as for spectroscopy applications. By utilizing 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 center 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.

Note on spectral plots:
In the past, each shipment has included a spectral plot for every filter and every lot code in the shipment. In an effort to be more eco-friendly, we will no longer be including these plots with each shipment. If you require spectral plot data, please see here for more information.
