CWS (Custom Wavelength Selector) is a custom model of the optical tunable bandpass filter where users can specify the wavelength and bandwidth they require. A truly Innovative device for spectroscopy and spectral imaging.

But beware, the wavelength and bandwidth are fixed. This device is intended for specific use and for OEM integration into devices.

The Custom Wavelength Selectors (CWS) are ideal for any imaging, microscopy, or illumination applications. The bandpass performance of LSL-FWS-M-CWS provides benefits for matching the emission profile of a new fluorophore or the emission spectrum of a fluorochrome shifted slightly due to factors such as the particular excitation wavelength being used.

Custom Wavelength Selectors are simple, rugged, optomechanical devices that are factory set to your exact specifications without the usual time and cost associated with obtaining custom bandpass filter performance.

Key advantages of the manual tunable filter LSL-FWS-M-CWS:
- Custom bandpass performance
- Customer defined transmission bandwidth (FWHM)
        - minimum: 2-5 nm
        - maximum: 13-15 nm
- Customer defined center wavelength from 255-1700 nm
- Circular aperture: 5 mm or 10 mm
        - A5: 5 mm, suitable for lasers, supercontinuum lasers
        - A10: 10 mm, suitable for light sources with large beam size (tungsten-halogen, plasma, LED)
- Compact optomechanical device (40 x 76 x 40 mm)
- Simple integration into microscopes, telescopes, cameras, light sources and other photonic instruments with our accessories
- High out of band blocking (OD 5) avoids unwanted spectral leakage and associated background noise typical of liquid crystal-based filtering systems

* For the optimal performance of the FWS, the incident light should be collimated.

* 255 – 348 nm range can block up to 600 nm.
