FAQ No. FAQ01253

Primary Contents


How long does the Laser Diode (LD) last?


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.
