Chips 4 Light GmbH
Characterization of laser diodes
Chips 4 Light not only offers a broad selection of laser diodes, but also additional services for characterizing and selecting individual diodes. We offer customized measurement of TO38 and TO56 under controlled temperature conditions according to:
Wavelength
Optical power
Constant power measurement via external photodiode
CW (continuous wave) and QCW (quasi-continuous wave -> pulsed) measurements
Beam measurement: Measurement of the elliptical laser beam with a high-resolution camera for characterization of the parallel and perpendicular beam angles, measurement of the viewing angle, alignment definition of TO lasers, bare laser chips, and customer-specific setups
Our specially developed measurement station enables us to characterize individual TO housings according to power and wavelength. This means that our customers receive specifically specified products and do not have to purchase a wide range of variations in trays, which typically contain large quantities.
For example, according to the data sheet, a typical green TO56 laser has a peak wavelength deviation of approximately 20 nm. The diodes we measure can be selected with a tolerance of only 2 nm. You get exactly what you need, and that is virtually unheard of anywhere else.
