BXZ-10.6-2-6X is a continuous zoom beam expander specifically designed for 10.6μm carbon dioxide lasers. Manufactured with high-quality zinc selenide (ZnSe) optical material and precision coating technology, it delivers excellent transmittance and a high damage threshold in the far-infrared band.

The key advantage of this product is its continuous zoom function, offering an adjustable magnification range from 2× to 6×, allowing flexible adjustment of laser beam diameter without the need for lens changes to suit various processing requirements. It features a 16mm entrance aperture and a large 96mm exit aperture, accommodating larger input beam diameters. The beam expander has a compact length ranging from 205.8mm to 212.4mm, facilitating easy system integration.

This beam expander adopts a Galilean optical design with no internal focal point, effectively avoiding air ionization risks in high-power laser applications, making it particularly suitable for high-power CO₂ laser systems. Zinc selenide (ZnSe) material offers extremely high transmittance and low absorption at the 10.6μm wavelength, and combined with advanced anti-reflective coatings, the total transmittance can exceed 97%. Adjustable divergence allows optimal matching with different laser systems.

The BXZ-10.6-2-6X is widely used in laser marking, cutting, engraving, medical equipment, scientific research, and laser measurement applications where high flexibility is required, making it an ideal optical solution for dynamic beam size adjustment in COâ‚‚ laser systems.
