Industrial Blue Dot Laser
FEATURES:
1. Designed and manufactured in Taiwan, ensuring exceptional quality and durability.
2. This module is an industrial-grade product that integrates an aspherical glass collimating lens, a blue laser diode, and an ACC driver circuit into a compact and durable stainless steel housing.
3. Delivers a high-quality laser spot, supports a wide operating temperature range, and offers a 10,000-hours lifespan for reliable performance in diverse environments.
4. Compact design with an integrated Auto-Current-Control (ACC) driver circuit for safe and consistent laser output.
5. A visible blue wavelength producing a sharp, high-contrast beam. Blue lasers are highly visible and effective for projection and fluorescence excitation.
Laser products manufactured by Quarton inc. meet the international safety standards:

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.
