Note: Your Quotation Request will be directed to Modulight, Inc..

The ML5740-658 from Modulight’s ChiliLase Series is a Multi-Chip Red Laser Module that operates at 658 nm. It delivers 2.5 W of CW optical output power and has a threshold current of 0.4 A. This single emitter laser requires a DC supply of 8.6 V and consumes less than 1.6 A of current. It uses a photodiode for power monitoring and a thermistor and TEC for temperature monitoring.

The fiber-coupled laser is available in a module that measures 38 x 48 x 22 mm with SMA-905/ST/FC connectors and is suitable for industrial and medical applications such as illumination, imaging, pumping, aesthetic treatments, fluorescence, and photodynamic therapy.
