12V PWM 450nm 10W Blue Laser Diode Module with Collimated Beam

BU-LASER presents the 12V DC PWM-controlled 450nm 10W high-power collimated blue laser module—a fully integrated, plug-and-play industrial laser light source specially optimized for desktop DIY laser engraving, cutting, marking, and wood/acrylic precision processing. Adopting genuine high-power blue laser diode, built with constant current drive, precision glass collimating lens, efficient passive heat sink,  it delivers stable 10W CW output, ultra-narrow collimated spot, strong material ablation ability, and 12V wide compatibility, perfectly matching all mainstream small desktop laser engraving machines, CNC laser cutters, and DIY laser engraving kits.

Core Advantages for Desktop Laser Engraving

1. 450nm Pure Blue High-Energy Wavelength

450nm ±5nm deep blue wavelength features ultra-high photon energy, with 3–5× higher absorption rate on wood, acrylic, leather, paper, plastic, and painted metal surfaces compared to infrared/red lasers. Achieves instant charring, fast engraving, and deep cutting with minimal heat-affected zone (HAZ), no material yellowing or over-burning.

Excellent anti-ambient light performance: stable clear laser spot under indoor workshop lighting, no blurring or power attenuation, suitable for daily continuous engraving production.

Narrow spectral linewidth ≤5nm FWHM, pure beam output with no stray light, ensures fine edge engraving and smooth cutting kerf.

2. 10W High Power Stable CW Output & Strong Processing Capacity

10W real optical power CW continuous output (not electrical power), meets heavy-duty desktop engraving demands: supports one-pass cutting of 8mm solid wood,  3mm plywood, and ultra-fine deep engraving on leather, cardboard, PCB, and coated metals.

Full power adjustable range: 0–10W stepless power tuning via PWM signal, freely switches between low-power fine engraving and high-power deep cutting modes.

3. 12V Single DC Power Supply & Standard PWM Control

Ultra-convenient 12V DC wide voltage input, directly compatible with 12V power adapters, battery packs, and desktop engraver motherboard power systems; no additional high-voltage power supply required, greatly simplifies DIY machine wiring.

Industry-standard PWM brightness modulation (0–100% duty cycle) with fast response ≤50μs, fully adaptive to GRBL, Marlin, Smoothieware, and all mainstream engraving controller firmware, realizing real-time power linkage with engraving speed.

Built-in integrated constant current laser driver inside the module: external only needs 12V power + PWM signal wiring, no separate driver board, fully integrated all-in-one design.

4. Precision Collimated Beam Design (Key for Desktop Engraving)

Equipped with high-precision multi-element glass collimating lens group, realizes ultra-low divergence collimated beam:

Ultra-compact, round, uniform spot with no scattered halo, guarantees ultra-fine engraving lines , sharp contour marking, and clean, burr-free cutting edges for desktop precision processing.

Fixed focus optimized for desktop engraving working distance (50–300mm), no manual focus adjustment required after installation.

5. Industrial-Grade Efficient Passive Heat Dissipation & Rugged Structure

Thickened anodized aluminum alloy finned heat sink, large-area passive heat dissipation . No cooling fan, zero noise, no dust suction, perfectly fits sealed desktop engraver chassis.

Compact integrated aluminum housing , standard M4 threaded mounting holes on rear flange, plug-and-play installation on all desktop laser lifting mounts.

Fully sealed optical window with AR anti-reflective coating, dustproof, scratch-resistant, and oil-proof, prevents dust contamination on collimating lens for long-term stable beam performance.
