Product Name: VersaTest characterize optoelectronic device

Product Description

The VersaTest systems serve for the characterization of optoelectronic devices, such as semiconductor lasers. For the testing of semiconductor laser, the standard measurements include: optical power as a function of the current, forward voltage, roll-over current, kink detection, farfield distribution and optical spectrum. An optical inspection of the devices can be included as a further option.

The carrier which holds the laser bars or dies is designed for maximum stability and highest thermal and electrical conductivity. The surface is precisely polished to ensure perfect thermal and electrical contact. 

Depending on the system requirements, the devices can be operated at different temperature levels.

The VersaTest selects all the data of the individual samples and puts them together with the corresponding serial numbers. Bar codes can also be read. Measurement data is stored and the data of different tests can be compared (for example before and after burn-in cycles). Additionally, data from different machines can be exchanged.
