Osram logo

OSRAM Opto Semiconductors is a key player in the field of visible InGaN (Indium Gallium Nitride) lasers. OSRAM Opto Semiconductors offer leading product performance and innovative packaging. Thanks to their excellent beam quality, OSRAM laser diodes are ideally suited for the optical imaging of light. Not only that, but their small package size is particularly beneficial to highly compact systems, such as pico projectors. OSRAM laser diodes offer high efficiency and long lifetime: due to their excellent efficiency (ratio of light produced compared to electric power consumed), the temperature increase experienced by blue InGaN lasers during operation is kept to an absolute minimum, allowing them to deliver a long life – up to 10,000 hours at 40 °C.
