I. Common faults and impacts of TSL-570 laser

Fault type Possible cause Impact

Abnormal wavelength offset Grating motor damage, control circuit failure Wavelength offset, inaccurate test data

Optical output power reduction Laser attenuation, component pollution Insufficient signal strength, affecting measurement accuracy

Equipment cannot start Power module failure, motherboard is completely damaged, production line interruption

Communication error Interface board failure, software compatibility issues Unable to remote control, automated process blocked

Temperature control failure TEC cooler failure, radiator system abnormality Wavelength stability decreases, long-term damage to laser

II. Our maintenance process - accurate diagnosis, efficient repair

1. Fast fault diagnosis (1-2 hours)

Lock the scope of the faulty equipment through logs and self-test codes

Use professional instruments (spectrum analyzer, power meter, etc.) to detect laser output performance

Grading inspection of optical path, circuit, and control system

2. Solution

Laser attenuation aging → Replace the original LD module and rearrange
