BXZ-532-1-4X is a high-precision 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.

The key advantage of this product is its continuous zoom function, offering an adjustable magnification range from 1× to 4×, 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 12mm, the exit clear aperture is 18mm, supporting a maximum input beam diameter of 4mm. The transmittance exceeds 96%.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 a damage threshold of 5 J/cm² (10ns pulse), capable of withstanding long-term stable operation in high-power laser systems. 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-532-1-4X 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.
