Silicon Galvanometer Mirror
Silicon galvanometer mirrors are core reflective elements in laser-scanning systems, precision-manufactured from single-crystal silicon. Used with scanning-galvanometer motors, they rapidly deflect beams in CO₂ laser marking, engraving, and cutting. High reflectivity, high damage threshold, and low thermal expansion support prolonged high-power operation, making them preferred mirrors for industrial CO₂ scanning systems. Incident spot size, overall dimensions, and coatings can be customized for mainstream motors. Some standard versions are stocked, and special specifications can be developed.

Overview
Silicon galvanometer mirrors are core reflective elements in laser-scanning systems, precision-manufactured from single-crystal silicon. Used with scanning-galvanometer motors, they rapidly deflect beams in CO₂ laser marking, engraving, and cutting. High reflectivity, high damage threshold, and low thermal expansion support prolonged high-power operation, making them preferred mirrors for industrial CO₂ scanning systems. Incident spot size, overall dimensions, and coatings can be customized for mainstream motors. Some standard versions are stocked, and special specifications can be developed.
Applications
CO₂ marking/engraving equipment: scanning reflectors for nonmetal marking, leather engraving and acrylic cutting. Industrial systems: beam deflection in CO₂ cutting, welding and drilling. Red-indicator equipment: silicon galvanometer mirrors support both CO₂ lasers and red positioning light. Research/teaching: components for laboratory CO₂ scanning experiments and demonstrations.
Key Features
High reflectance/low loss: 10.6μm CO₂-laser HR coating, R>99.8%, reduces energy loss and improves productivity. High-power tolerance: single-crystal silicon conducts heat rapidly for prolonged high power without easy thermal deformation/damage. Broadband compatibility: red aiming-light (630-650nm) AR coating, reflectance R>80%, supports red positioning. Precision fabrication: flat mirrors avoid deflection aberrations for scan precision/spot consistency. Mainstream incident-spot sizes/profiles fit most galvo motors directly. Custom dimensions, thicknesses and other-band coatings suit nonstandard equipment. V. Yasi Optical advantages. Stable substrates: pure, dense single-crystal silicon with good heat conduction ensures high-power stability. Precision flatness/finish reduces scattering and preserves scan accuracy. Mainstream stock enables rapid delivery. Custom sizes/thicknesses/bands serve diverse equipment. Every galvo mirror inspected for reflectance, flatness and surface quality.
