1) Un-mounted Single-element Scan Lenses, STSL Series
STSL scanner lenses specially designed and optimized for use in CO2 laser 2-axis galvo-scanner systems with full beam diameters of up to 15.0mm.
2) Mounted Single-element Scan Lenses, STDC Series.
3) Mounted 2-element Scan Lenses, STC Series
The mounted 2-element scan lenses are 2-element designs for CO2 laser beams up to 15mm diameter, supplied complete in a mechanical housing.
The most common type of beam expander is derived from the Galilean telescope which usually has one negative input lens and one positive output lens. The input lens presents a virtual beam focus at the output. For low expansion ratios (1.3-20 times) the Galilean telescope is most often employed due to its simplicity, small package size and low cost.
