Blue Dot Laser Module
FEATURES:
1. High-Precision Circular Dot: Maintains a dot size of less than 3 mm from 0 to 5 meters, ensuring accurate alignment, positioning, measurement, and guidance.
2. Superior Visibility: ideal for high-precision industrial, scientific, and commercial applications.
3. Robust Construction: Stainless steel housing provides enhanced durability and environmental resistance, while a high-precision glass lens ensures optical clarity.
4. Built with high precision glass lens.
5. Industrial use laser modules have 10,000 hours working life.

Quarton inc. places emphasis on laser safety
About APC (automatic power control) circuit:
The Laser output power must be stable especially in safety reason.
But the Laser power is related to the Junction Temperature (Tj) of the LD. It means that as the different Tj, the Laser power will be increased or decreased.
An APC (automatic power control) circuit is used to compensate the varying Laser output power to constant.
As shown in the picture, The principle of the APC circuit is monitoring portion of the laser light from the LD by the built-in PD and real-time feedback to control the laser output power constant and safety.
