Manual beam expanders VEX series used to increase or decrease laser beam diameter. Standard or custom-made laser beam expanders for use in the UV, visible, and NIR spectral ranges have a unique mechanical sliding-lens design, ensuring high pointing stability and minimal dimensions.
These variable magnification (zoom) beam expanders are designed for required wavelength and each type of our beam expanders has a 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. Large input and output apertures allow the optical beam expanders to be used to produce diffraction limited expanded (or reduced) beams for a wide range of input beams.
