Endurance lasers do multi tests of all lasers.
Here is our demo stand
The basic principle of testing:
1-Laser Run Mode. Within 1.5 hours, the laser turns on randomly with different PWM duty cycles. After 1.5 hours, the Status LED flashes. The test run stops, the lasers turn off. 0-Manual PWM duty cycle adjustment. Using a resistor, the duty cycle of the PWM output signal changes from 0 to 99%. 2-PWM off.
