Focusing lens element GCO-15 series

laserprecision

Air-spaced focusing lenses are designed to focus the high-power radiation emitted by lasers. The lenses are optimized for high precision applications such as used in laser machining systems for welding, cutting, drilling and strutting. They can also be used for collimating the laser beam delivered by fiber. The Daheng’s air-spaced focusing lens product utilizes high quality triple lens elements which are optimized to obtain a diffraction-limited focus spot. With the design-specific optical coating, the lens system achieves transmission throughout at a designed wavelength up to 98%.
