Profile: ULO Optics (UK) provides CO2 laser optics and beam delivery equipment. Our CO2 laser optics are manufactured from ZnSe (zinc selenide), silicon (Si), copper (Cu), as well as zinc sulphide (ZnS), gallium arsenide (GaAs) and molybdenum (Mo). It includes menicus, plano-convex, plano-concave, aspheric, cylindrical, scanner & multi-element scanner lenses, beam combiners, curved partial reflectors and phase retarders. Beam splitters allow a beam to be split into two beams of differing power. The polarization needs to be considered when specifing a beamsplitter otherwise the reflected and transmitted beams will not have the correct power. We porvide a polarization insensitive coating which eliminates this problem for th 50:50 case.
