Fiber Laser Focus Lens The focusing collimating mirror focuses the light source parallel to a point, maximizing the energy of the light source at this point, allowing the object to burn or sublimate rapidly for cutting. Features: Standard high efficiency, low loss anti-reflectance. Double-sided AR coating process, high transmittance. High-quality crystal, high-temperature resistance. Serve & available time is long, easy & convenient to install. Fiber Laser Collimating Lens The collimating lens is a divergent angle compression of the diverging laser to achieve parallel optical transmission. Monolithic, multi-chip or aspherical lenses can be used according to different requirements. Features: Collimating lens is a composite lens to obtain the best optical quality and cutting effect. High transmission rate, ultra-low absorption, can withstand 10,000 watts of power, high threshold of enthalpy loss. Consistency is good, the working distance consistency is greater than 99.5%. High laser transmittance, high damage threshold, can be applied with high power laser cutting. The collimation effect is good, less than 1/10 wavelength. [...]
