DESCRIPTION
By utilizing multiple liquid crystal variable retarders and polarizers, this tunable filter allows the user to switch between any wavelength from 420 to 730 nm. In addition to the tunability of wavelength, this filter also allows the user a choice of three different bandwidth sizes at each wavelength. Selecting a wider bandwidth, one can increase the overall transmission of broadband light whereas the narrow FWHM can pass only a few wavelengths from a broadband light source.
All tunable optical filters from Meadowlark Optics come with three components: the optical head, the controller, and the software necessary to run the tunable optical filter. This software can be installed and run on any Windows based PC through either the USB or serial port while using the provided FilterDRIVE software or commands in C++, MatLab or LabVIEW.
