IR Dot Laser Module
FEATURES:
1. M12 Thread & Wide Voltage Range: Designed with M12 threading for easy installation and supports Wide Voltage Compatibility: Operates at 10~36V, covering 12V, 24V, and 30V, meeting industrial standard requirements.
2. 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.
3. Extremely Small Circular Dot: Maintains a sharp, precise dot within 1 meter, making it ideal for high-accuracy applications.
4. Robust Construction: Stainless steel housing enhances durability and resistance to environmental factors.
Laser products manufactured by Quarton inc. meet the international safety standards:
USA: FDA Class I, II, IIIa
Japan: PSC(JQA)
Europe: EU60825, CE & TUV-GS
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.
