Optoelectronics Company – Laser diodes have built-in photodiode for optical output power monitoring Jan 30 2019 Semiconductors Learn More About The Product More news from OptoElectronics Print Article Jan 30 2019 Semiconductors The Optoelectronics Company is offering two single transverse mode 639nm laser diodes with built-in photodiode, from USHIO Opto Semiconductors, for optical output power monitoring in industrial applications – the HL63391DG and HL63392DG. Combining an output power of 200mW with 12% lower energy consumption, these new red laser diodes provide exceptional directivity and narrow monochromaticity as well as their small 5.6mm package. They are ideal as light sources for a mixture of optical applications such as laser levelling, distance measuring, position sensing and numerous medical applications. The devices consume 12% less power than equivalent conventional USHIO diodes due to an optimised laser structure, active layers and facet coating.
