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.

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.
