About Coated Lense
Binoculars
Binoculars consist of numerous air to
glass surfaces with each individual surface contributing
to the loss of light. Coated
lense binoculars help prevent the loss of
light (by up to 50%) with one or more of the
surfaces being coated with one or more layers of
anti-reflective coating.
Coated lense binoculars used to come
with a hefty price tag but now most binoculars come with
lens coatings in one form or another and top quality
fully multi-coated lense binoculars are often within the
price range of many users.
There are basically four grades of lens
coatings although some manufacturers have developed their
own, exclusive, high quality coatings which offer greater
durability and further improved light transmission with
other added advantages:
-
Coated lense binoculars means that one or
more surfaces are covered with one layer of anti-reflective
coating. If only one or a limited number of air to glass
surfaces are coated the binoculars will provide you
little more light transmission than no coating at
all.
-
Fully coated lense binoculars means that
air to glass surfaces are coated with one layer of
anti-reflective coating.
-
Multi coated lense binoculars means that
one or more air to glass surfaces are coated with multiple
layers of anti-reflective coating. As with lenses with a
single coating you have to be careful here as just one
surface could be coated!
-
Fully multi coated lense binoculars are
the best that you can buy. All air to glass surfaces are
coated in multiple layers of anti reflective
coating.
Fully coated lense binoculars can
increase light transmission from 50% to around 80 – 85%
which is now the norm for low cost binoculars. If you
want something a bit more special that will increase
light transmission to 95% or above then you want to go
for fully multi coated lense binoculars and, for extra
durability and advance quality viewing, take a look at
the exclusive coatings offered by some of the top
manufacturers. Bushnell Elite
binoculars come with Bushnell’s exclusive XTR technology
(60 layers of coatings on each prism) which delivers
99.73% light transmission per lense.
The difference between fully coated
lense binoculars and fully multi coated might not sound
that great but once you have owned binoculars with the
best quality optics and coatings you’ll never look back.
The light transmission, resolution and clarity of top
quality binoculars is amazing and the enhanced viewing
generally makes the higher price tag well worth
it.
