LD Testing & Sorting Service
LD TESTING & SORTING SERVICE (OEM) PROCESS FLOW
Laser Diode (LD, also called semiconductor laser) is a semiconductor device similar to a light-emitting diode (LED), and is characterized by a single waveform with narrow spectral width and highly directional light with uniform phase. Laser diodes now are widely used in various devices like barcode readers, illumination, advanced driver-assistance systems, autonomous vehicles (LIDAR), fiber optic communications, facial recognition system, 3D sensing, AR/VR etc.
With advanced R&D team and leading optical and electrical testing technology, FitTech provides completed laser diode testing solutions, include VCSEL, DFB, PD, FP, EML testing and sorting systems, and laser diode testing and sorting service.
