The TWOTREES 5.5W Optical Power 450nm Laser Module is a high-precision fixed-focus laser engraving module designed for fast, stable, and accurate engraving and light cutting applications. Built with an upgraded 40W laser structure and optimized optical system, this module delivers true 5.5W optical output with lower energy loss and longer service life. Using spot compression and beam aggregation technology, the laser produces a highly concentrated beam for fine engraving accuracy up to 0.01mm.

It supports multiple engraving modes including photo, text, scanning, outline, and pixel engraving, making it ideal for CNC laser engravers, DIY laser machines, and professional engraving setups. The aluminum alloy housing improves heat dissipation and durability, ensuring consistent performance during long working hours. Suitable for engraving stainless steel (surface marking), aluminum, wood, leather, plastic, bamboo, ceramics, rubber, and more, this laser module offers excellent efficiency and precision for creative and industrial applications.
