Ushio proudly announces the mass production and shipment of the new HL85022MG series laser diodes (LDs), which are characterized by high power, high efficiency, and excellent beam quality and are used as an infrared light source for night vision and ranging sensors.
Infrared LEDs in the 800 nm range are used as light sources for infrared illumination applications such as night vision devices, distance measurement sensors such as ToF (Time of Flight)*1, triangulation, and 3D sensing. Recently, the demand for accurate measurements over long distances in any environment has increased.
In order to meet these market requirements, Ushio achieved a further increase in output power and efficiency while maintaining good beam quality Ushio began mass production and shipment of the 250mW HL85022MG series in 850 nm band with an extended operating temperature range of -40°C to 75°C from November 2023.
This enables the HL85022MG series to be used in a wide range of applications in both extremely cold and hot environments.
With this product launch, Ushio will continue to contribute to a safer society in the future.
*1 ToF（Time of Flight ）
A method of distance measurement based on the time it takes for light emitted from a light source to be reflected by an object.
