Blue Dot Laser Module with TTL Modulation Function
FEATURES:
1. M12 Thread & Wide Voltage Range: Designed with M12 threading for easy installation and supports a 10~36V power supply for versatile integration.
2. TTL Modulation Function: Supports Continuous Wave (CW) to 10 kHz modulation, enabling high-speed operation, improved power efficiency, and enhanced precision and control.
3. Integrated Optics & Electronics: Built-in APC (Automatic Power Control) driver circuit ensures stable and safe laser output, while an aspherical glass lens provides a precise, tight dot across a wide temperature range.
4. High-Precision Blue Circular Dot: Maintains a dot size of less than 3 mm from 0 to 5 meters, ensuring accurate alignment, positioning, measurement, and guidance.
5. Robust Construction: Stainless steel housing enhances durability and resistance to environmental factors.

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.
