Blue High Power Laser Module

Model : VLM-450-91 LPB
Blue high power laser module- ideal for special lighting, laser marking, medical science application...etc.


1.  Blue Laser Diode module to provide large temperature operation range.

2.  This module has integrated optic, laser diode and APC driver circuit.

3.  APC driver circuit enables the laser output power safe and constant.

4.  Aspherical Glass Lens provides tight laser dot.

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.

* Operation temperature: it means within this temperature range, the laser spot/line will not be affected to change the spot size/line width. It can still work over this range, but the laser spot size or laser line width will be larger.

** Laser module housing is an electrical positive surface, it is imperative that contact between the laser module and the machine be avoided. This is to prevent damage from the machine electrical leakage. Surge protected power supply to the laser module is strongly recommended.
