Fixed ratio beam expanders FEX series are used to increase laser beam diameter. The FEX model diversity cover the UV, visible and NIR spectral ranges. These compact beam expanders are designed for required wavelength and have divergence adjustability.
All optical elements of beam expanders are made of fused silica with high LIDT coatings and provide stable and reliable performance even using them with high power lasers.
