F-theta lenses

F-theta lenses F-theta lenses used for laser marking/scanning/ engraving application. scanning area is linear relationship between the input scan angle and the focal position on a flat plane. Since spot size is proportional to focal length; we can provide short focal length scanning Ftheta lenses. We use fused-silica material to provide better optical transmission than standard BK7 glass. By this user can operate with less laser power, extending laser lifetime, and also reduces heat build-up in the lens due to absorption, extending lens lifetime.
We have scanning lens from 266 to 10600 nm wavelength.
