제품 설명
CO₂ Laser ZnSe Plano-Concave Lens
Eternal Optics manufactures precision CO₂ Laser ZnSe Plano-Concave Lenses designed for 10.6 μm CO₂ laser systems and infrared optical applications. Made from high-quality Zinc Selenide (ZnSe) material, these negative focal length lenses provide excellent infrared transmission, low optical absorption, and reliable performance for laser beam expansion, divergence control, and optical beam shaping.
A ZnSe Plano-Concave Lens is a negative lens designed to diverge incoming laser beams and adjust beam propagation characteristics. It is commonly used in CO₂ laser optical systems where precise control of beam divergence, beam diameter, and optical path optimization is required.
Our 10.6µm ZnSe Plano-Concave Lenses feature wavelength-specific AR (Anti-Reflective) coatings optimized for CO₂ laser wavelengths, ensuring high transmission efficiency, reduced reflection loss, improved laser performance, and long operational lifetime in industrial laser environments.

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.
