BXZ-1064-2-8X-A is a high-performance continuous zoom beam expander specifically designed for 1064nm near-infrared lasers. Manufactured with high-quality UV fused silica (UVFS) optical material and precision coating technology, it delivers excellent transmittance and a high damage threshold in the near-infrared band, capable of withstanding long-term stable operation in high-power fiber lasers and solid-state lasers.

The key advantage of this product is its continuous zoom function, offering an adjustable magnification range from 2× to 8×, allowing flexible adjustment of laser beam diameter without the need for lens changes to suit various processing requirements. It features a 13mm entrance clear aperture and a large 60mm exit clear aperture, accommodating larger input beam diameters. The mechanical housing features a fixed-length design with a length of 162-169mm, facilitating easy system integration and optical alignment.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 laser systems. UV fused silica material offers extremely high transmittance at the 1064nm wavelength, and combined with anti-reflective coating (Ravg<0.25%), the total transmittance exceeds 97%. Adjustable divergence allows optimal matching with different laser systems. The "A" suffix indicates performance optimization based on the standard version. A locking mechanism is incorporated to maintain stable magnification after focusing adjustment.

The BXZ-1064-2-8X-A is widely used in laser marking, precision cutting, laser welding, laser engraving, LiDAR, scientific research, and laser measurement applications requiring high flexibility, making it an ideal optical solution for dynamic beam size adjustment in high-power laser systems.
