IR Circular Dot Laser Module
FEATURES:
1. Extremely Small Circular Dot: Maintains a sharp, precise dot within 1 meter, making it ideal for high-accuracy applications.
2. Robust Construction: Stainless steel housing ensures durability and resistance to environmental factors.
3. Built with high precision glass lens.
4. Customized focus within 1 meter available please direct contact us.
5. Integrated Optics & Electronics: Features a built-in APC (Automatic Power Control) driver circuit for stable and safe laser output, along with an aspherical glass lens for a precise, tight dot across a wide temperature range.
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.
