PG&O offers a full range of anti-reflection coatings from 350nm to 1700nm. We have standard broadbands, V-Coatings, and double V-Coatings matched to a variety of substrates, as well as single layer MgF2. All can be shifted to your wavelength and angle requirements.
This is our standard broadband shifted slightly to the left. Note that it
performs well on both BK-7 and Fused Silica.
Theoretical
single layer Magnesium Fluoride coating at 8° angle of incidence
in the mid-visible spectrum on SF-10 (Nd = 1.728).
This
coating requirement was for average reflection of less than 1.5% in the visible
and less than .75% at 1.064µ at 45° for
average polarization.
This customer had parts made of both BK-7 and Fused Silica
and needed reflection to average less than 0.5% per surface from 500-900nm
at normal incidence.
This
is a V-Coating at 364nm @ 45° angle of incidence on NG-1 where the
reflection for both S & P polarizations needed to be less then .5%.
A
V-Coating for 1.064µ at 8° angle of incidence on B-270.
A
very low and wide V-Coating for the telecom industry. Per the customer’s
request, the outside layer is quartz.
