Feb/Mar 2018The Flexible Wavelength Selector (FWS) Auto series from Spectrolight Inc. features computer control of center wavelength, bandwidth and wavelength scanning via a USB link and graphical user interface software.

The FWS is a wavelength filtering device that combines the precision tunability and adjustable bandwidth of a traditional monochromator with the circular uniform aperture of a bandpass filter. Several models of FWS Auto are available with tuning ranges to cover the visible spectrum, each with FWHM bandwidth adjustable from 2 to 20 nm and apertures of up to 10 mm diameter. All models provide high out-of-band extinction.

The FWS Auto emphasizes operational simplicity and the software screens provide two operational set and scan modes. The set mode allows the user to independently set the center wavelength and the bandwidth. The scan mode allows the user to choose start and end scan wavelengths, step size, step speed and bandwidth. The software automatically controls the internal compensation optic in the FWS Auto in both modes so that there is no change in output angle or lateral shift in the position of the output. The FWS Auto can be used to filter in either the source or imaging side of an optical system, providing unique functionality in microscopy, illumination, machine vision, life sciences instrumentation and hyperspectral imaging. The compact dimensions of the FWS Auto enable simple integration for both original equipment manufacturers and end users in these applications.More products
