Galvo Scanning Mirrors
Lightweight, low-inertia mirrors for laser engravers and galvo scan heads. The most-replaced optic in any galvo system.
- ● Low inertia for fast scanning
- ● Protected silver or gold coatings
CO2 Laser Mirrors (Mo / Si)
Molybdenum and silicon mirrors for CO2 cutters and engravers. Mo lasts longer; Si reflects more.
- ● 19mm / 20mm / 25mm standard sizes
- ● Mo for durability, Si+Au for reflectivity
Polarizing Beam Splitter Cubes
PBS cubes for splitting or combining polarized beams. The workhorse component of interferometers and laser setups.
- ● Standard 12.7mm / 25.4mm cubes
- ● Broadband and laser-line variants
