532nm beam expanders for green laser marking machine

The 532nm beam expander is mainly used to enlarge the diameter of the light beam and improve the collimation degree of the beam. The transmission type beam expander is usually composed of two or more optical elements. Its core function is to adjust the size and divergence angle of the light beam, thereby optimizing the beam quality and meeting the requirements of different application scenarios.

    Characteristics of 532 beam expander:

    1.Made of fused silica, it offers excellent optical performance and stability.
    2. Designed and manufactured with high precision, ensuring the wavefront distortion across all systems is less than 1/10 wavelength.  
    3. Utilizes a Galilean design, eliminating internal focusing to ensure high-quality beam transmission and imaging.

    The advantages of the 532 beam expander are as follows:

    1. Precise beam expansion ratio: It can precisely control the expansion ratio of the light beam, meeting the requirements of high-precision applications.
    2. Excellent optical image quality: The optical performance is outstanding, with the imaging quality reaching the diffraction limit level, ensuring that the light beam is uniform and clear.
    3. High transmittance: The single-side transmittance of the lens remains at 99.8% on average, minimizing energy loss and improving the efficiency of the light beam.
    4. High damage threshold: Offers excellent durability and reliability.
    The material used for the 532 beam expander: It is fabricated from fused silica  material.

    Applications

    1.In laser processing applications, the beam expander can transform the laser beam with a certain 
    divergence angle into a collimated (parallell) beam, thereby using the focusing lens to obtain a 
    Small high power density spot; 
    2. ln laser ranging system, the beam expander can be used to maximize the collimation of the laser to 
    obtain the ideal long-range measurement effect; 
    3. Beam expander can change the beam diameter for different optical instruments and equipment; 
    4. The combination of a spatial filter and a beam expander can make the asymmetric spot energy distribution symmetrical and make it more uniform.
