BXZ-532-2-8X-A 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. The beam expander is optimized for diffraction-limited performance, maintaining excellent beam quality throughout the entire 2× to 8× magnification range. It features a 14.5mm entrance clear aperture and a 30mm exit clear aperture, accommodating larger input 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. Optical elements feature high-performance anti-reflective coatings with transmittance exceeding 97.5% and a damage threshold of 10 J/cm² (20ns pulse). 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. The housing features a fixed length of 152.9mm, with internal translation of optical elements maintaining constant overall length for easy system integration and optical alignment. The "-A" suffix indicates performance optimization based on the standard version.

The BXZ-532-2-8X-A 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.
