In-Line VCSEL Testing返回
Article by Dr. Tobias Roesener
In the mass production of laser diodes such as VCSEL, high-resolution array spectroradiometers are an efficient alternative for in-process inspection in a 24/7 production environment. Compared to established scanning measurement techniques, they also guarantee high throughput volumes and reliability in the industrial environment: their configuration means high mechanical stability and integration times in the order of just a few milliseconds for CCD and microseconds for CMOS detectors. Measurements of laser diodes with a pulsed operating mode are also possible.
