Wavelength Selector Auto, LV, 358 - 628 nm, Poly

The Flexible Wavelength Selector (FWS) Auto is a tunable filter which utilizes TwinFilm™ technology to provide a simple software control (scanning or setting) of the center wavelength and the bandwidth via a USB connector. The center wavelength tuning range can be as wide as around ~ 500 nm or as narrow as ~ 50 nm depending on the specific model. The bandwidth can be adjusted from around 2 to 16 nm also depending on the specific model.

Key product advantages:

• Fast software controlled wavelength tuning
• Software bandwidth adjustment (FWHM 2 – 16 nm)
• Circular aperture
• High (10⁶) out of band extinction
• Compact

Features

Uniform Circular Aperture: Uniform circular aperture simplifies spectral filtering of images and illumination sources, avoiding the limitations of a typical monochromator slit geometry.

Simple Software Control: Automated and simple software control of the center wavelength and the transmission bandwidth. Supports custom wavelength scanning, setting and stepping.

Simple Integration: Compact collinear geometry simplifies integration into microscopes, telescopes and cameras and other common photonic instruments.

High Extinction: High (10⁶) out of band extinction avoids unwanted spectral leakage and associated background noise typical of liquid crystal based filtering systems.
