    Fixed ratio beam expanders FEX series are used to increase the laser beam diameter. The FEX model diversity covers the UV, visible, and NIR spectral ranges.

    These compact beam expanders are designed for the required wavelength and have divergence adjustability.

    All-optical elements of beam expanders are made of fused silica with high LIDT coatings and provide a stable and reliable performance even using them with high power lasers.
