CO₂ Laser Telecentric Scan Lens
Telecentric scanning lenses are special configurations in which the arrangement of optics is designed to focus down the beam so that it is always perpendicular to the flat field. This is accomplished by ensuring that the system 'stop' is located at the front focal point of the lens system. The 'stop' is located at the position where the beam is deflected from the axis. In a single-axis scanning system, this location is at the scanning mirror. For two-axis scanning, the stop is mid -way between the mirrors. Adaptors for major scan head providers are available upon request.

CO₂ Laser Singlet F-Theta Scan Lens
F-Theta lenses are commonly used in conjunction with galvanometer scanning mirrors in laser engraving, cutting, and marking systems. Typically the F-Theta distortion of the lens is kept less than 1% so that it is able to produce a precise spot in the flat field on the image plane.

CO₂ Laser Doublet F-Theta Scan Lens
Doublet F-Theta scanning lenses provide better performance than a singlet. It has more even spot size and less spot distortion over the scan field. We use ZnSe or GaAs for this series of scan lenses. Lens adaptors for major scan head providers are available upon request.

CO₂ Laser Beam Expander
Beam expanders developed for CO laser are made by ZnSe material which has the highest transmission for CO laser. We provide a wide range of magnifications from 1x to 20x. With dedicated mechanical structure, the internal lenses don’t rotate during adjustment, which ensures the best alignment accuracy. Adjustable ring with scales makes it more convenient for user’s operation. UniBET series beam expanders are developed for higher power (>100w) CO2 laser without water cool. It has consistent outer dimension and connecting thread M30x1. A laser beam expander is designed to increase the diameter of a collimated output beam. It is used in applications such as laser scanning, interferometer and remote sensing. BET-WC Series water cool beam expanders are developed for even higher power (>200W) CO lasers with consistence in outer dimension and water pipe connection. MiniBET series have the same external diameter of 20mm, thread M16x0.75 and it is widely applied in compact CO laser system.

CO₂ Laser ZnSe Plano-Convex Lens
Focusing lenses are used to focus laser beam. The objective of focusing the laser beam is to concentrate the laser power for material processing. ZnSe Lenses are widely used for COlaser applications because of its low absorption at infrared wavelengths as well as its visible transmission.
