Flexible Wavelength Selector Poly Laser Version
The Flexible Wavelength Selector is a unique tunable filter that employs TwinFilm™ technology to deliver the tunability and adjustable bandwidth of a grating monochromator, together with the imaging advantages of a circular aperture filter. FWS Poly models feature complete software control of wavelength and bandwidth via a USB link and simple software interface. The laser version is compatible with beam size of up to 3 mm.
Key product Advantages
> Adjustable center wavelength
- can be tuned or set as wide as ~500 nm.
> Adjustable bandwidth
- from 3 nm to 15 nm (nominal)
> Circular uniform aperture
