Ushio presents its new 850 nm, 250 mW high power HL85022MG laser diodes (LDs) series featuring high optical output power, high efficiency and excellent beam quality as an infrared light source for night vision sensors and distance measurement sensors.
LDs using wavelengths in the infrared range have been applied in a wide range of fields.In particular, infrared LDs in the 800 nm infrared range are used as a light source for infrared illumination applications such as night vision and as a sensor light source for distance measurement, as represented by triangulation and 3D.
Currently Ushio offers a line-up of 50 mW products that have achieved high-quality beam characteristics in the 830 nm and 852 nm range using our unique design technology, and these have been well appreciated by a large number of customers.
In recent years, there has been growing demand for longer range and higher performance in night vision applications, as well as the practical application of LDs for long-distance measurement sensors using the ToF (Time of Flight) method.
To meet these market requirements, LDs in the relevant wavelength band are required to have even higher optical output power and efficiency without losing their good beam quality.
Therefore Ushio has developed the HL85022MG series with a wavelength of 850 nm by redesigning the conventional chip structure and expanding the optical output power to 250 mW while maintaining ideal Gaussian shape good beam quality.
In order to meet a wide range of ambient temperatures, the operating temperature range has been expanded from -10 to 60°C to -20 to 75°C, which allows for use in a wide range of applications in both cold and hot areas.
With this additional line-up added to its 800nm band product range, Ushio will contribute to safer, more secure society in the future.
