Multi-Layer Antireflection
Coatings (MLAR)
|
 These rugged
multilayer antireflection coatings provide low level reflectance and
excellent durability and adhesion for all substrate types. They find
application in precision optical systems, telecommunications, optical
fibers, missile systems and ophthalmic lenses. The coatings are produced
with low temperature processes compatible with most types of glass and
plastic. Deposited with
ion-assistance, they have an extremely dense and compact film
structure that exhibits superior moisture stability and durability.
Standard designs are offered to cover most popular wavelength ranges;
custom designs are available for any region from the UV to the far IR
wavelengths
Single Band AR
Coatings
|
 |
|
These two-layer designs provide extremely low reflectance over a narrow range for any of the laser and telecommunication wavelengths through the visible and NIR regions. Reflectance is < 0.1% at the design wavelength, and the coatings survive all durability and environmental testing per MIL-C-675. The ion-assisted deposition process allows the temperature to be restricted to less than 100°C, making it compatible with sensitive substrates such as plastics and optical fibers.

Dual Band AR
Coatings
|
|
These multilayer
designs provide very low reflectance at two separate wavelength bands
anywhere within the visible and NIR spectra. Reflectance is < 0.2% at
each of the design wavelengths, and the coatings survive all durability
and environmental testing per MIL-C-675. The ion-assisted deposition
process allows the temperature to be restricted to less than 100°C, making
it compatible with sensitive substrates such as plastics and optical
fibers.

Broad Band AR Coatings
(BBAR)
|
|
These multilayer designs provide very low reflectance over a broad range of wavelengths anywhere within the visible and NIR spectra. Reflectance values depend on the exact wavelength range; typical for the visible region would be R<0.3% average, R<0.5% maximum. The coatings survive all durability and environmental testing per MIL-C-675. The ion-assisted deposition process allows the temperature to be restricted to less than 100°C, making it compatible with sensitive substrates such as plastics and optical fibers.
