Where to Buy Wavelength-tunable Light Sources

Optometrics, a Dynasil company, offers its TLS as a convenient and affordable integrated system consisting of a Mini-Chrom monochromator and an efficient, power stabilized broadband tungsten halogen light source with a variable aperture. The versatile design allows for the selection of manual or computer controlled versions, a spectral range from 360 – 1000 nm, a customizable bandwidth, as well as fiber optic input adapters and cables for the output.

The Stuttgart Instruments Alpha system is a modular, wavelength-tunable laser covering the 700 nm to 20 µm spectral range. It provides ultrafast pulses at MHz repetition rates and milliwatt- to watt-level power. Due to its excellent passive long-term stability, outstanding performance at the shot-noise limit and broad spectral range, it is ideally suited for sensitive IR applications.

The Alpha system can be configured optimium for your application. Its basic version is tunable from 1.35 µm to 4.5 µm, but can be upgraded to higher power, to the VIS (700 – 980 nm), the NIR (1.1 – 1.4 µm) and the MIR range (4.5 – 20 µm). Each module is field upgradable, and the entire system is fully automated and controlled via a user-friendly GUI.

Alpes Lasers designs and manufactures single-mode mid-IR lasers with wavelength tuning over more than 10 cm⁻¹. Broad-gain lasers with wide tuning in an external cavity are also offered.
