Description
Specifications

FEATURES:

1. High-Quality Manufacturing: Designed and manufactured in Taiwan, ensuring superior durability and long-lasting performance.

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. Green Circular Dot Laser: Delivers a precise dot less than 3 mm from 0 to 5 meters, ensuring high-accuracy alignment, positioning, measurement, and guidance. Green lasers are significantly brighter than red lasers, making them ideal for industrial, scientific, and commercial applications.

4. CW to 10K HZ stable power output for demanding power and speed are of important.

5. Robust Construction: Stainless steel housing enhances durability and environmental resistance, while a high-precision glass lens ensures optical clarity.

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.
