ProPhotonix Ltd of Salem, NH, USA, a designer and manufacturer LED illumination systems and laser diode modules for OEMs and medical equipment companies (as well as a distributor of laser diodes for Panasonic, Ushio, Osram, QSI, and Sony), has announced the development of a new 405nm laser module with an external photodiode, which is claimed to provide excellent output power control over an extended product life-time.

The firm says that 405nm laser diodes are not typically packaged with an internal monitor photodiode, because the photodiode typically degrades over time. The new design includes an external photodiode designed to deliver excellent output control in the 1-150mW range. The durable photodiode has high sensitivity to 405nm radiation for more precise control of laser output.

"This new 405nm laser module demonstrates ProPhotonix's ability to overcome design challenges and deliver custom laser diode modules tailored to customer's application needs." says Jeremy Lane, managing director of Laser Operations at ProPhotonix.

ProPhotonix is exhibiting in booth 1100 at the SPIE Photonics West 2015 event in San Francisco, CA, USA (10-12 February).
