Benchtop 4-Channel Light Source
The Benchtop 4-Channel Light Source is a multi-channel laser system that integrates four independent semiconductor lasers. The four laser channels can be configured independently; the output power, operating wavelength, and linewidth of each channel can be customised according to customer requirements. It is suitable for experiments, tests, and system integration scenarios that require multi-wavelength and multi-channel laser outputs. The instrument is equipped with both RS-422 and USB communication interfaces, enabling serial communication with a PC for remote control and system data integration. The entire unit is debugged and performance-calibrated before delivery, allowing users to operate it with a "one-click start" without complex optical or parameter adjustments, thus lowering the threshold for deployment and use.
Product features:Four independent laser channels;Flexible customisation of parameters;Dual communication interfaces;Independent channel control
