Description:
F-theta lenses simplify scanning systems by ensuring a linear relationship between the input scan angle and the focal position on a flat plane. The line includes the 355nm fused-silica type F-Theta lens with a short focal length. The short focal length allows users to obtain the smallest possible spot size to improve system resolution. The fused-silica provides better optical transmission than standard N-BK7 glass, particularly for UV and near-UV wavelengths. The increased transmission allows systems to operate with less laser power, extending laser lifetime, and also reduces heat build-up in the lens due to absorption, extending lens lifetime.
The introductions provide a full line of telecentric F-Theta lenses for use in scanning systems such as laser marking and 3D prototyping. Telecentric lenses are designed to eliminate the perspective error found in conventional lens systems, increasing the depth of field for focusing. The combination enhances the ability of scanning systems to handle non-flat surfaces and makes them ideal for cutting or drilling when the process must remain perpendicular to the surface, as in semiconductor and solar panel processing.
F-Theta Scanning Lenses are commonly used in laser marking, engraving, and cutting systems. Used in conjunction with a galvanometer, beam expander, and Nd:YAG or CO2 laser source, F-theta lenses are designed to provide a flat field at the image plane of the scanning system.
Our Nd:YAG F-Theta Lenses feature multiple elements for the ultimate in image resolution. An air-spaced design and high efficiency AR coatings guarantee excellent throughput and durability. An industry-standard M85 threading on all F-theta lenses allows for easy mounting and simple retrofitting of OEM systems.
