Sell CO2 f-theta lenses/ Scan lenses

Description

CO2 f-theta lens/ Scan lens STSL scanner lenses specially designed and optimized for use in CO2 laser *-axis galvo-scanner systems with full beam diameters of up to *5.0mm. Mirror sets appropriate for use with beam diameters up to *5mm require an increase in mirror separation in comparison with smaller mirrors. These changed optical conditions are catered-for by the STSL 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) *8mm diameter and 3mm edge thickness. The lens material is ZnSe.

Transmission: >*9.6% when AR/AR coated for *0.6Î&frac*4;m Coations: Standard AR/AR coatings are very low absorption, which helps to minimize thermal lensing effects when used with high intensity laser beams. Laser damage threshold: ***0W/mm (+/**0%) This is equivalent to **8km/cm2 at 5kw laser power.
