Flexible Wavelength Selector Manual

Overview Basic CenterLine High Resolution Related Products Order Now!

Flexible Wavelength Selector – Manual Basic, CenterLine and High Resolution.

Three manual models feature manual adjustment of the center wavelength, transmission bandwidth and beam offset compensation. For High Resolution (HR) and Basic (B) models, the bandwidth can be manually adjusted from around 1.5 nm to 16 nm. The bandwidth of the CenterLine (CL) model is fixed at ~ 16 nm (nominal)

Basic

The center wavelength, the bandwidth and the beam direction offset can be adjusted/controlled manually by featuring three knurled knobs; Two for adjusting the center wavelength and the transmission bandwidth, the other for compensating the beam direction offset.

CenterLine

The center wavelength with a fixed bandwidth and the beam direction offset can be adjusted/controlled manually by featured two knurled knobs; one for adjusting the center wavelength with a fixed bandwidth of around 16 nm (nominal), the other for compensating the beam direction offset.

High Resolution

Both the center wavelength and bandwidth can be adjusted separately by the multi-rotation manual knobs with the maximum quality resolution. Compared with the FWS-Basic model, it is possible to make a more minute adjustment of the center wavelength and bandwidth with this model.

Flexible Wavelength Selector - High Resolution

The high resolution manual format features two precision multi-rotation dials for adjusting the center wavelength and the transmission bandwidth. The third knob is used for compensating the beam direction offset. High resolution models are ideal for chemical imaging type applications, where the wavelength can be rapidly adjusted and set to an emission or absorption peak of the sample.
