The Flexible Wavelength Selector Poly (Poly-RED, Poly-BLUE) is a tunable bandpass filter which utilizes TwinFilm™
technology to provide a simple software control (scanning or setting) of the center wavelength and the bandwidth
via a USB communication. With both high (10-6) out of band rejection and excellent (>75%) transmission, the Flexible
Wavelength Selector (FWS) is a simple, turnkey solution for various applications that require specific wavelength
excitation and detection throughout the extended wideband spectrum (255 – 1700 nm). Poly is simple to integrate
with broadband light sources, cameras, and other instruments, resulting in Tunable light source and Hyperspectral
imaging application.
Poly is divided into the Poly-RED and the Poly-BLUE product lines, depending on the bandwidth control function.
The Poly-RED model can control center wavelength and bandwidth (FWHM) simultaneously. For the Poly-BLUE
model, only the center wavelength can be controlled with the fixed bandwidth of 20 nm (nominal).
Also, Poly has different product lineups depending on input beam size. The Poly-A5 models have beam aperture of
5 mm and is mainly used in case of broadband light source with small beam size such as supercontinuum lasers.
For large beam sizes such as LEDs and lamps the Poly-A10 model with an aperture size of 10 mm is recommended.

4. Operation (Raman mode, optional)
4.1 Raman mode (Optional function)
Customers who purchase the Raman model of Poly-RED can use Raman mode to detect specific Raman band for
imaging. The Raman model can select two modes (Stokes, Anti-stokes) in the options tab.
*NOTE : The Raman model is only available for the Poly-RED model.
www.spectrolightinc.com
4.2 Setting the center Raman shift and bandwidth
- Since Stokes Raman shift and anti-stokes Raman shift represent the same information as mirror images, this
manual mainly explains Stokes Raman shift.
- FWS operates on Wavelength Base, and in order to use it in Raman mode, it operates by converting wavelength
to wavenumber. Because the wavenumber is inversely proportional to its wavelength, the specified wavenumber
value may not be the exact wavelength at which the Poly can move. Therefore, the Poly sets the wavelength
value closest to the user-specified wavenumber.
4. Operation (Raman mode, optional)
1. Excitation Wavelength (nm) : enter the desired Raman Excitation Wavelength
2. Center Raman Shift (cm-1) : enter the desired Center of Raman shift
3. Bandwidth Raman Shift (cm-1) : enter the desired Bandwidth of Raman shift
4. Real Center Raman Shift (cm-1): indicates the actu al moved value of Raman shift wavelength

4.3 Scanning across a certain Raman shift range
1. Enter the following
- Excitation Wavelength (nm) : enter the Raman Excitation Wavelength
- Start Raman Shift (cm-1) : Raman shift to start scanning
-End Raman Shift (cm-1) : Raman shift to end scanning
-Bandwidth Raman Shift (cm-1) : bandwidth during the scanning
-Step (cm-1) : step size of the scan in wavenumber
-Time delay (sec) : set the time delay between each individual wavelength steps
- Repeat time (count) : number of full scans
2. Go : click to start scanning
3. Stop : click to stop scanning
*Note : Although the Poly has calibration data at intervals of 0.2 nm as the wavelength base, there may be instances
where a specific wavenumber does not have a corresponding value because the wavenumber is inversely proportional
to its wavelength. Consequently, scanning with a constant wavenumber step may not yield optimal results.
For scanning of a specific Raman band, it is recommended to use Preset mode to scan a specific band.
