Hangzhou Brandnew Technology Co., Ltd. is one of China's leading manufacturers and premier suppliers of advanced 2w 940nm vcsel laser chip. Operating a state-of-the-art factory, we specialize in the entire production spectrum—from high-performance chips, TO/F/C Mounts, COS, and MCC bars, to robust stacks and advanced fiber-coupled solutions.
2W 940nm VCSEL Laser Chip
VCSEL (Vertical-Cavity Surface-Emitting Laser) is a semiconductor laser that emits laser light perpendicular to the top surface, unlike traditional edge-emitting lasers, which emit laser light from the edge. This emission mode of VCSEL allows testing and problem handling at any stage in the manufacturing process, thereby improving production efficiency and product quality
