Optogama introduces Motorised laser beam #expanders, #collimators & beam #reducers used to increase or decrease laser beam diameter, adjust divergence. Standard or custom made Galilean type laser beam expanders and resucers for use in the UV, visible, and NIR spectral ranges has a unique mechanical sliding-lens design, ensuring high pointing stability and minimal dimensions.
These variable magnification (zoom) beam expanders and reducers are designed for required wavelength and each type of our beam expanders has a divergence adjustability. As an optional module laser beam attenuation unit can be integrated together for BDS series systems.
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.
