BXZ-532-2-8X-B is a high-performance continuous zoom beam expander specifically designed for 532nm green 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 green wavelength band, capable of withstanding long-term stable operation in high-power green laser systems.

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. According to product specifications, the entrance clear aperture is 11mm and the exit clear aperture is 60mm, with a housing length of 190mm. The "-B" suffix indicates a large output aperture design (Big output diameter), providing larger clear aperture compared to the standard version to meet applications requiring larger beam diameters.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 green laser systems. UV fused silica material offers extremely high transmittance at the 532nm wavelength, combined with high-performance anti-reflective coatings achieving transmittance exceeding 95%. The zoom ring is engraved with magnification markings, allowing precise beam expansion and collimation by rotating to the corresponding mark for simple and intuitive operation. Adjustable divergence enables optimal matching with different laser systems, and a locking mechanism is incorporated to maintain stable magnification after focusing adjustment.

The BXZ-532-2-8X-B is widely used in green laser marking, precision cutting, LED chip processing, photovoltaic scribing, scientific research, and laser measurement applications requiring high flexibility, making it an ideal optical solution for dynamic beam size adjustment in 532nm green laser systems.
