12V PWM 450nm 5W Blue Laser Head for Laser Engraver

The 12V PWM 450nm 5W Blue Laser Head Kit—a turnkey, plug-and-play solution engineered for desktop and industrial laser engravers/cutters. Optimized with PWM power modulation, 12V low-voltage compatibility, and 5W high-efficiency blue output, this kit delivers precise, fast engraving and cutting performance for wood, acrylic, leather, and other common materials, with seamless integration into mainstream engraver control systems.

Core Advantages for Laser Engraving & Cutting

450nm Blue Wavelength: High-Efficiency Material Processing

• 450nm (±5nm tolerance) blue light achieves 2–3x higher absorption rate on non-metallic materials (wood, acrylic, leather, cardboard) compared to 1064nm IR lasers, ensuring crisp engraving details and clean cutting edges with minimal heat-affected zones (HAZ).

• 5W CW output delivers energy density ≥5000mW/cm² at the focal point, enabling fast engraving speeds (up to 1000mm/s) and precise cutting (acrylic ≤3mm, wood ≤5mm in a single pass) for small-batch customization and industrial prototyping.

12V PWM Modulation: Flexible Power Control

• Full-range PWM power adjustment: 0–100% power tunable via 1–20kHz PWM signal, compatible with all mainstream engraver controllers (e.g., GRBL, MKS, Smoothieware). Adjust power dynamically for different tasks—low power (5–20%) for delicate engraving, high power (80–100%) for deep cutting.

• 12V DC low-voltage input matches the power supply of most desktop laser engravers, eliminating the need for voltage conversion modules; over-current/over-voltage protection is built in to prevent controller damage.

Turnkey Kit Design: Plug-and-Play Integration

The kit includes all essential components: 5W blue laser head, active cooling fan, adjustable focus lens, aluminum mounting bracket, connection cable, and PWM control driver board. No extra accessories required for installation.
