How long does the Laser Diode (LD) last?Last Updated: September 13, 2018
The LD lasts for approximately 50,000 hours at 40°C with failure rate of 10%.
It lasts for approximately 100,000 hours at normal temperature (Approx. 25°C).
The life of semiconductor laser has approx. 50,000 hours.
(Failure rate: 10%, ambient temperature: 40°C)
*Semiconductor laser is operates the pulse of one-fifth duty for keeping the long life.
*The life of Semiconductor laser becomes the approx. 50% by increasing the 10°C.
For your information, the Smart Sensors has the function of laser life degradation detection.
