Pentamaster’s Optical VCSEL Wafer Test Handler is our next generation cutting edge full turnkey solution designed to test the electrical & optical characteristics of packages such as VCSEL, LED and LIDAR in wafer-level. It uses an integrating sphere to measure & test the optical power efficiency & wavelength of the laser emitted from the optical device sequentially with very short test time. It is also capable of performing Near & Far Field tests by using NIR sensitive camera with Conoscopic Lens to determine the emitting diameter, mode emission characteristics as well as the maximum emission angle of the optical device.
