Hangzhou Brandnew Technology Co., Ltd. is one of China's leading manufacturers and premier suppliers of advanced 850nm 4mw vcsel diode to46. 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.
850nm 4mW VCSEL Diode TO46
Overview
Features
Vertical-Cavity Surface-Emitting Lasers
Low electrical parasitic TO-46 package
High performance GaAs PIN photodiode with separate transimpedance amplifier
Low bias currents and voltage
High reliability and easy to collimate
Note
Reflow soldering can be operated only one time. During the temperature ramp-up, no forces
may be exerted on the LD which could deform or damage them. After soldering completed, please
also do not process until the product temperature ramp down to room temperature.
