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.
Who Needs FWS-Poly ?
For users who need precise spectral control in compact, flexible systems.
1. Build a tunable light source from white light
- Select wavelengths in 1 nm steps
- Replace AOTFs, monochromators, or LLTFs with software control
- Use safely with femtosecond or high-power lasers
2. Enable precise imaging or analysis
– Create a hyperspectral imaging system
– Analyze specific wavelengths with high accuracy
– Adjust bandwidth dynamically for various conditions

- Poly-BLUE: Tunable center wavelength with fixed FWHM (10 nm or 20 nm)
Refer to the table below to choose a model that fits your CWL range and bandwidth needs.
Step 2 : Choose the appropriate aperture size for your light source
| Poly-A5 | 5 mm |
Suitable for supercontinuum lasers |
| Poly-A10 | 10 mm |
Suitable for light sources with large beam size(tungsten-halogen, plasma, LED) |
