Product Highlights


Demonstration of Poly's Operation


The data above demonstrates the operational capability of Poly, highlighting its
accurate ability to freely select both the center wavelength and bandwidth.
Who Needs FWS-Poly ?
For users who need precise spectral control in compact, flexible systems.
1. Build a tunable light source Using broadband light source(white light)
- Select the wanted wavelengths in 1 nm steps via software control
- Replace AOTFs, monochromators, or LLTFs
- Can be used safely with femtosecond and high-power lasers without incurring damage.

2. Enable precise imaging or analysis
– Create a hyperspectral imaging system
– Analyze specific wavelengths with high accuracy
– Adjust bandwidth dynamically for various conditions

Choose Your Model: Poly-RED or Poly-BLUE
Step 1: Select a filter model based on your target wavelength and desired bandwidth configuration
The Poly series includes two types
- Poly-RED: Tunable center wavelength with adjustable FWHM (2–15 nm)
- 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) |
