THIN FILM COATINGS Spherical Lenses Anti-Reflection Coatings Coatings Anti-Reflection Coatings High Reflection Coatings Lenses Windows Optical Fiber Endfaces Custom Coatings We offer a wide range of Anti-Reflection coatings which may be applied to any of our glass or fused silica lenses or windows to reduce reflection losses. Through use of our Ion Assisted Deposition (IAD) process we also specialize in AR coatings on optical fiber endfaces. Low temperature IAD coatings may be applied to most fiber endface terminations. Pre and post coating inspection is performed in our dedicated facility to ensure high quality. Our “Super-V” Coatings represent the ultimate in low reflection coatings (R<0.1%) for narrowband applications. We also offer laser line V Coatings, Broadband Multilayer AR Coatings, Multiband AR Coatings, Telecom AR Coatings and Single Layer AR MgF2 Coatings. Standard coatings may be ordered by simply appending a coating suffix to the product number and specifying the number of sides to be coated. For more complex requirements we suggest that you call - our applications engineers will be pleased to advise you on the best coating for your needs. Standard Anti-Reflection coatings are listed in the following table. Specifications & Tolerances On BK-7 Substrates: Super V: V Coating: ( ­ <325nm) λ V Coating: ( λ>325nm) Multiband AR: Broadband AR: MgF2 AR: R<0.1% per surface at designated wavelength R<0.5% per surface at designated wavelength R<0.25% per surface at designated wavelength R<0.25% per surface at designated wavelengths R<0.6% per surface over the designated range R<2.5% per surface over the designated range Durability and Laser damage threshold depend on the substrate so please see the later sections of this catalog for these specifications. The curves on the following pages show typical single surface reflectance for each of the specified coating types. ORDERING & TECHNICAL SUPPORT
