Tunable Laser Source

Based on Photon etc’s filtering technology, our Tunable Laser Source allows for fast wavelength selection from stable and powerful Leukos-SM-20-OEM super-continuum sources. The available spectral range is from UV to NIR, with a FWMH as low as 0.4 nm. A large tuning range makes highly precise (up to 0.05 nm) and accurate (up to 0.1 nm) wavelengths easily achievable.

Photon etc’s technology and design make it an ideal tool for work in instrumentation labs as well as on telescopes. New developments in super-continuum white laser technology allow the full visible or NIR wavelength range to be produced by a single source. Output power can reach up to 100 μW/nm.

Custom Tunable Laser Sources are also possible with other Leukos super-continuum sources, such as SP-20-OEM or SP-8-OEM.
