    Zoom Beam Expander Features:

    1. Flexible multiple adjustment
    2. Outstanding imaging quality
    3. Compact structural design
    4. High-precision adjustment mechanism
    The zoom beam expander is made of fused silica, a high-purity amorphous silica. It has excellent optical transparency across UV, visible, and near-infrared spectra. With high heat resistance, it performs well in harsh conditions. Its low dispersion reduces chromatic aberration, enhancing imaging quality. These properties make fused silica ideal for manufacturing zoom beam expanders, meeting the high-precision and high-stability requirements of various optical systems.

    Applications

    The zoom beam expander is a flexible optical system with continuous variable magnification, meeting diverse laser application needs. Its independent divergence angle adjustment optimizes beam collimation without changing the magnification. Widely used in laser processing, scientific research, and high-power laser systems, it satisfies stringent requirements for beam size, divergence angle, and quality.
