For all the optical componentswe provide, we use only ion-beam-sputtered(IBS) coatings because our IBS coatings aresignificantly more dense, durable, and ruggedthan conventional coatings. The IBS coatingprocess is both accurate and repeatable, resultingin precision coatings that are easy toclean, chemically resistant and insensitive tomoisture and other environmental factors.For broadband, dispersion-free multi-photonmicroscopy mirrors, see page 11.For polarizing beamsplitters, see pages 13–14.These are just some of the types of coatings that PPCdoes every day on in-house and customer-supplied substrates.High-energy ion-beam-sputtered thin films that areaccurate, durable and environmentally stable are ourforté, and we can turn around parts in as little as 48hours!Typical Dichroic CharacteristicsTypeLong-wave pass, short-wave pass orcustomOperating WavelengthUV, Visible & NIR (250–3000 nm)Angle of Incidence0°, 45° or customReflectivity>99.9%Transmission>98%On/Off Tolerance5%AR on Side 2
