445nm Blue Laser Module 1500-3000mW Adjustable Focus for CNC Engraving

This laser module is designed as an accessory for CNC engraving machines and similar equipment. It emits blue light at a wavelength of 445nm. The pulse power is rated at 1500-3000mW, and the actual power is approximately 60% of pulse power. A built-in driver board provides adjustable constant current, and the module requires a current of 2A or above. It operates on DC 3.7V to 5V. The spot can be adjusted for focus, and the compact 12mm x 45mm size allows it to be mounted in tighter setups. The module is supplied in yellow. Because it has relatively high power, it must be used with care and with a qualified heat dissipation system.

Features and Construction

The module combines a 445nm blue light source with a built-in adjustable constant current driver board. Its pulse power rating is 1500-3000mW, with actual power around 60% of that figure. The 12mm x 45mm size makes it a compact component for CNC engraving machine accessories. The focus spot can be adjusted, and the module operates from DC 3.7V to 5V with a current requirement of 2A or above.

Material and Build

The product is built around a laser tube that emits blue light at 445nm. The built-in driver board is adjustable and provides constant current, helping to regulate operation when the correct current of 2A or above is supplied. The module is supplied in yellow. No further material details are provided in the source information, so only the stated construction and electrical characteristics are confirmed here.

Size and Practical Fit

The module measures 12mm x 45mm. This compact size is suitable for integration into CNC engraving machine accessories where space is limited. The adjustable focus allows the spot to be set as needed, and the DC 3.7V-5V operating voltage and 2A or above current requirement should be matched to a suitable power supply. The 1.5-metre focus guidance helps users set a safe working distance.

Uses and Placement

This module is intended for use in CNC engraving machines and comparable equipment. It can serve as a focused blue light source for engraving tasks where the user controls the setup and provides adequate heat dissipation. The compact size and adjustable focus make it suitable for fitting into machine assemblies that can accommodate a 12mm x 45mm module.

Event or Professional Use

In workshop, makerspace, or professional engraving setups, the module can be used as part of a CNC machine accessory chain. The 445nm wavelength and 1500-3000mW pulse power are the key specifications. A qualified heat dissipation system must be installed during operation to avoid overheating and burning out. Users should also ensure the current supply meets the 2A or above requirement and the voltage stays within DC 3.7V-5V.

Everyday Home Use

For home CNC or hobby engraving projects, the module offers a compact 12mm x 45mm form and adjustable focus. It should only be used with proper heat dissipation and within the stated electrical limits. The power is relatively high, so it must not be directed at people or flammable materials. Long periods of use should be avoided to prevent damage to the head from high temperature.

Benefits and Buying Value

The main value of this module lies in its stated specifications: 445nm blue light, 1500-3000mW pulse power, adjustable focus, and a built-in adjustable constant current driver board. Its compact size and DC 3.7V-5V operating range make it a practical component for compatible CNC engraving machine accessories, provided the user supplies adequate heat dissipation and follows the safety precautions.

Reuse and Low Maintenance

With correct installation and a qualified heat dissipation system, the module can be used as part of repeated engraving tasks. The built-in driver board helps maintain constant current when supplied with 2A or above. To reduce the risk of damage, the module should not be used for long periods, and the focus should be set within 1.5 metres. These precautions are stated in the source information and should be followed to support ongoing use.

Why Choose This Product

Choose this module if you need a 445nm blue light laser module with 1500-3000mW pulse power, adjustable focus, and a built-in adjustable constant current driver board for a CNC engraving machine. It measures 12mm x 45mm, runs on DC 3.7V-5V, requires 2A or above, and is supplied in yellow. It is not suitable for prolonged use without heat dissipation, and it must never be aimed at people or flammable materials.
