Ushio, Inc. has recently launched a new high-efficiency, low operating current HL65261MG series laser diodes (LDs). This addition to Ushio’s 660 nm product line enables the continued proliferation of sensor devices equipped with red LD light sources.
Laser distance sensors span a wide range of industrial uses, from traditional applications in construction and civil engineering to the increasing factory automation (FA) of manufacturing lines, logistics systems, and other unmanned operations. In particular, Time of Flight (ToF) distance sensors use red or infrared lasers to provide long distance detection and highly accurate positioning capabilities.
For ToF sensor applications, a high pulse light output is required to support highly accurate, long distance sensing. However, there is also a demand for improved LD efficiency and lower operating current in order to create more efficient measurement devices (e.g. photo-electric sensors).
To meet rising market demands, Ushio has reviewed the chip structure of its existing 660 nm products. Through the improvement of output efficiency and significant reduction of the reactive current, Ushio improved the wall plug efficiency by 22% and reduced operating current by 35% for the HL65261MG series.
