355nm UV beam expander

The transmissive beam expander is generally composed of two or more optical elements and is mainly used to adjust the size and divergence angle of the light beam. It can significantly enhance the collimation of the light beam, thereby reducing the spot size after focusing and thus improving the efficiency and precision of the light beam.

    The 355nm beam expander has the following characteristics: It is designed and manufactured with high precision, ensuring that the wavefront distortion of all systems is less than 1/10 of the wavelength, resulting in excellent optical performance. It adopts a Galilean structure, which eliminates internal focusing and effectively ensures beam quality and transmission stability.
    The advantages of the 355nm beam expander are as follows:
    1. **Accurate Expansion Ratio**: It can precisely control the expansion ratio of the light beam, meeting the requirements of various application scenarios.
    2. Superior Optical Quality**: The optical performance is excellent, with imaging quality reaching the diffraction limit level, ensuring the uniformity and consistency of the light beam.
    3. High-Precision Coaxiality: The coaxiality of the product is controlled within 3 arc minutes, ensuring the symmetry and stability of the light beam.
    4. High Transmittance: The transmittance of each surface of the lens is greater than 99.8%, minimizing energy loss to the greatest extent.
    5. High Damage Threshold: Allowing it to withstand high-energy-density lasers and ensuring a long service life.
    The material used for the 355nm beam expander: It is fabricated from fused silica  material.
