Semrock VersaChrome Tunable Bandpass Filters | An in-depth comparison of the major types of tunable filters in terms of key performance parameters |
Semrock's VersaChrome Edge™ filter unlock virtually unlimited spectral flexibility for fluorescence microscopy and hyperspectral imaging as well as 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.
Input the desired Center-Wavelength (CWL) and Guaranteed-Minimum-Bandwidth (GMBW) or Full-Width-Half-Maximum (FWHM) to achieve a required passband to calculate which filters and rotational angles to use to achieve this result.
