Ushio HL65261MG series: High-efficiency laser diodes for sensing applications
Ushio, Inc. has introduced a series of visible wavelength laser diodes, HL65261MG / 62MG / 64MG, which offer high-efficiency and a low operating current, perfect for sensing applications such as laser distance sensors and Time of Flight (ToF) distance sensors.
There is growing market demand for improved laser diode efficiency and lower operating current to create more efficient measurement devices. For ToF sensor applications in particular a high pulse light output is required to support extremely accurate, long-distance sensing.
In response Ushio has reviewed the chip structure of its existing 660nm laser diodes such as the HL6501MG 658nm 30mW laser diode. By improving their output efficiency and significantly reducing the reactive current, Ushio has improved the wall plug efficiency by 22% and reduced the operating current by 35%. The result is the HL65261MG series 658nm 85mW AlGaInP laser diodes.
The HL65261MG / 62MG / 64MG series of laser diodes is the recommended and much improved replacement for HL6501MG laser diodes.
