IRVINE, Calif. — The FWS-Basic Flexible Wavelength Selectors from Spectrolight Inc. combine the wavelength tenability and adjustable bandwidth of a traditional monochromator with the circular, uniform aperture of a bandpass filter.
The devices feature simple manual control of wavelength and bandwidth with an aperture of up to 10 mm. They also feature high optical efficiency, integrated alignment compensation, sharp wavelength cut-off and high out-of-band extinction.
Several models are available with tuning ranges to cover the visible spectrum, and FWHM bandwidth is adjustable from 1.5 to 20 nm. Applications include microscopy, machine vision, and hyperspectral imaging.
