Product Highlights

This data shows the tunability of CWL and FWHM.

Once the wavelength, FWHM, and time delay are set, the system accurately outputs the configured wavelength.

1) Specified center wavelength (CWL) tolerance for Poly-RED and Poly-BLUE: ±1 nm.
2) Specified full width at half maximum (FWHM) tolerance: ±1 nm for Poly-RED, ±2.5 nm for Poly-BLUE.
3) OD 7 up to 600 nm for F00-F02 filters; for blocking beyond this range, dedicated out-of-band blockers such as WS-BL400UV and WS-BL1700SWIR are available..
4) Transmission efficiency values are based on filters with a 10 nm full width at half maximum (FWHM). At wavelengths below 400 nm, efficiency remains ≥50%.
5) Scanning speed represents time required for a single wavelength-to-wavelength transition, depending on step size.
 

Choose Your Model: Poly-RED or Poly-BLUE

The main difference between the Poly-RED and Poly-BLUE lies in how the bandwidth can be adjusted.

The available tuning range for each selected wavelength is as follows

* Poly-UV model/F00,F01,F02 Model can block up to 600 nm.
* For the optimal performance of the FWS, the incident light should be collimated.
* Do not use the product on its side or upside down. It must stay upright with the base fully in contact with the floor.
