Spectrolight Tunable Bandpass Filters – Precision Wavelength Selection for Research & Industry
Looking for a high-performance tunable optical filter in India? LaserQuant brings the innovative Spectrolight Flexible Wavelength Selector (FWS) series to researchers, OEMs, spectroscopy labs, hyperspectral imaging developers, Raman spectroscopy users, and photonics professionals across India.
The Spectrolight FWS utilizes patented TwinFilm™ technology to provide real-time control of both center wavelength (CWL) and bandwidth (FWHM) across a broad spectral range from 255 nm to 1700 nm, with high transmission (>75%) and excellent out-of-band blocking (OD10).
Why Choose Spectrolight Tunable Filters?
- Continuously tunable wavelength selection
- UV, VIS, NIR & SWIR coverage (255–1700 nm)
- Adjustable bandwidth from 2–15 nm (selected models)
- High transmission efficiency (>75%)
- Excellent out-of-band blocking (OD10)
- No calibration or alignment required
- Compatible with lasers, LEDs, tungsten-halogen, plasma, and supercontinuum light sources
- Ideal for hyperspectral imaging, Raman spectroscopy, fluorescence studies, machine vision, and optical research
