ZnSe lenses with one cylindrical surface may be made in either circular or rectangular shapes, both as plano-convex or plano-concave. ULO Optics offers a standard range of cylindrical lenses per the specifications below. Custom optics can be made to order. Standard sizes include 25.0 mm, 25.4 mm, 28.0 mm and 38 mm diameters. Custom cylindrical optics can be made up to 100 mm in size.

ULO Optics is an ISO certified company and quality is at the heart of everything we do. With a host of industrial affiliations you can rely on ULO to deliver.
Beam Expanders for 1μm lasers
ULO Optics are excited to introduce our new range of beamexpanders. Designed for low power (500w) lasers such as Nd:YAG and Yb doped fibre lasers operating near the 1μm wavelength. The beamexpanders are of Galillean design and use Multi-spectral Zinc Sulphide for the optics which has an absorption at 1μm of 0.0005cm−1 (Similar to ZnSe at 10.6μm).
ULO Exhibit in Munich
ULO Optics will exhibiting at this year’s Laser World of Photonics exhibition and would like to invite all existing and potential customers to come and visit our stand.

ULO Optics develops CO2 Brewster plate beamcombiner
In our new beamcombiner – C-BC-2, pairs of enhanced Brewster Windows are used to attenuate a linearly polarised CO2 laser beam. The Brewster plate acts like a polarising beamsplitter. The difference in reflectance also allows two perpendicular polarised beams to be combined into a single beam.
