Manual filter High Resoluition
- adjustable bandwidth: 2-15 nm (FWHM)
- total spectral range 255-1700nm: 255-290, 280-310, 310-350, 348-390, 385-435, 430-490, 485-550, 545-620, 615-700, 690-790, 775-890, 880-1015, 1000-1150, 1140-1310, 1300-1500, 1475-1700 nm
- aperture 5 or 10 mm
- high resolution, precise manual control
We propose 3 types of optical tunable bandpass filters that feature the independent control of both center wavelength and bandwidth by rotating the knobs on the device. They can be used with any collimated light source (Supercontinuum laser & broadband lamp) to produce a continuously tunable light source for spectroscopy and spectral imaging applications:
- Basic models provide manual control of wavelength and bandwidth via knurled knobs.
- CenterLine models provide manual control of wavelength with a factory pre-set bandwidth (10 or 20 nm FWHM).
- High Resolution models provide manual control of wavelength and bandwidth using multi-rotation precision dials.
* Manual models require a spectrometer for operation
The Flexible Wavelength Selector LSL-FWS-M- HighResolution is a manually tunable filter that provides smooth and precise manual adjustment; both the center wavelength and bandwidth are independently set with two multi-rotation manual dials for maximum resolution. An internal compensator maintains output alignment.
Key advantages of the manual tunable filter LSL-FWS-M- HighResolution:
- Broad wavelength tuning
- Precise bandwidth adjustment (FWHM 2 - 15 nm, nominal). Separate multi-rotation dials enable precise manual adjustment of both the center wavelength and the transmission bandwidth (Gear 27:1)
- 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 50 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.
* UV models F00-F02 can block up to 600 nm.
* Manual models require a spectrometer for operation
