Cylindrical Lenses

PPD manufactures custom, precision optics such as cylindrical lenses and cylindrical mirror substrates for medical instrumentation, semiconductor processing and high energy laser applications in the ultra-violet (UV), visible (VIS) and near-infrared (NIR) wavelength regions. Coated and uncoated optics are available from 5 mm to > 4” in size and in a variety of materials including fused silica, infrasil, N-BK7, CaF2, ZnSe, SF11 and other high index glasses. If your radius of curvature is not yet determined, contact us for information on existing fabrication tooling and tolerances, or send us your design specifications for a fully custom lens or mirror quotation.
 
Low-loss ion-beam-sputtered anti-reflection (AR) coatings with reflectivity less than 0.1% per surface and low absorption high reflector mirror coatings are available on PPD lenses or can be applied to customer supplied substrates. PPD uses only IBS thin film coating technology because it is a repeatable process which results in coatings that are durable, stable and easy to clean.
