CO2 Laser Scan Lenses (f-theta lenses)

(1) Un-mounted Single-element Scan Lenses, TSL Series

TSL 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. Mirror sets appropriate for use with beam diameters up to 15mm require an increase in mirror separation in comparison with smaller mirrors. These changed optical conditions are catered-for by the TSL series. These single-element lenses are designed to represent the best achievable compromise for on-axis and off-axis aberrations, field flatness and F-theta characteristics, obtainable using single-element spherical-surface designs of (standard) 48mm diameter and 3mm edge thickness.

(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. These lenses give excellent F-theta performance, with resolution (focused spot size) at, or very close to the diffraction limit over a flat image plane. Variation of spot size (standard deviation from average spot size over the full scanned field) is minimal.
