DOCTER® Long-range Optics Competence from Future and Tradition
DOCTER® Binoculars breathe an air of tradition and modern times.
The production site in Southern Thuringia is where observation optics
characterized by high quality standards come into being.
The interaction of optical know-how and fine mechanical precision
forms the basis for these high-performance products.

DOCTER® Binocular Engineering
Roof prisms – also called straight view binoculars, permit a slender design. Due to the prism
alignment, eyepiece and lens are arranged in one line (straight view).
Porro prism binoculars exhibit a very compact overall length and ergonomically convenient
handling due to the 90° angular offset of their prisms. The prism alignment permits an enlargement
of the lens distance and thus a more spatial impression.
Both design principles guarantee the highest degree of transmission, brilliance, colour fidelity,
contrast and edge definition.
Porro prism system
DOCTER® binoculars are available in two prism designs: roof prism and porro prism.

ED LensesThe use of ED lenses guarantees a true to original colour reproduction
and an increased sense of contrast. The picture seems clearer, more
focussed and spatial. ED is the abbreviation for "Extra low Dispersion
Glass“. Special lenses reduce the color fringes, thus guaranteeing a
high degree of detail perceptibility.
FocussingDOCTER® binoculars are equipped with different focussing versions.
The range comprises models with central focussing (CF) or individu-
al focussing (iF).
Suitability for Spectacle WearersDOCTER® binoculars have a large eye relief distance, which makes
them particularly suitable for spectacle wearers. The entire field of
view is available to spectacle wearers. The individual binocular-eye-
distances can be adjusted, either by turning over the rubber eye
cups or by twisting the "twist up“ eyepieces in three latching steps.

Experience a Wide-angled View of Nature
DOCTER® 8 × 42 ED The light binoculars for stalking, trekking and outdoors.
The DOCTER® ED binocular models with 42-mm lens opening convince by their functional design. An open hinge
connects the two halves of the binoculars. The "through grip" allows you to conveniently hold the binoculars with
one hand, while simultaneously operating the focussing mechanics. The sturdy, water-pressure tight and yet light
housing offers maximum protection to the lenses and mechanical components inside. The ED high-performance
lenses guarantee an impressive viewing experience with brilliant, sharply contoured and highly contrasting imaging.

Top Class lenses for the Discerning Customer
DOCTER® 8 × 58 B/CF The raised hide binoculars for the nocturnal hunter.
DOCTER® 8 x 58 stands for light intensity, high transmission performance and absolute detail perceptibility under unfavo-
urable light conditions. The lens opening of 58 mm, a dielectrically phase-corrected prism system and a 5-lens eyepiece
as well as the coating of all optically effective lens elements with DOCTER®multitop guarantee perfectly sharp images.
The water-pressure tight, nitrogen-filled casing consists of a high-strength synthetic polymer and together with the slip-
proof sheathing guarantees the longevity of lenses and mechanical system.

Overcoming limits
DOCTER® 7 × 40 B/GA The binoculars for special tasks.
Apart from their excellent optical performance, the models of the DOCTER® B/GA line are characterized by their extreme
sturdiness in respect of mechanical and climatic environmental influences. These binoculars were developed and pro-
duced according to military standards and can thus also be used in areas where other binoculars are stretched to their
limits. The advantages of the roof prism design manifest themselves in particular in the compact design and handy sha-
pe. The use of high-performance lenses with specially developed coating layers achieves peak values as far as resolution,
edge definition, contrast and brilliance are concerned. The robust, shock-absorbing rubber sheathing reliably and safely
protects the lenses and mechanical system that are designed for extreme stresses.

The individual eyepiece focussing (iF) is safe and reliable
to operate. The focussing range between - 7 dpt to +7
dpt makes it possible to adapt the eyepiece to almost any
pair of eyes. The soft telescopic eye cups optimally adapt
to any face contour and excellently screen distracting light
from the side.

DOCTER®NOBILEM Binoculars for any Possible use
The NOBilEm series offers top class binoculars for any possible use. The wide range of NOBilEm binocular models
is used in many areas of application. All models are operated with a porro prism system, thus providing highest
image quality. The high-performance coating DOCTER®multitop combined with the connection of the prism elements
achieves the highest possible light transmission. High contrast, edge definition and brilliance are the results of com-
bining top class lenses and precision mechanics.

DOCTER®NOBILEM offers the right kind of binoculars – even for special-needs users.
Apart from models with central focussing (CF), models with individual focussing (iF)
are also available. The visual acuity is adjusted separately for every eye. Once adjusted,
different observation distances can be imaged sharply without refocussing, depending
on the individual eye performance.
DOCTER®NOBILEM 7 x 50 B/GA (IF) with integrated reticle.
So as to be able to reliably estimate object distances, it is possible to equip
the NOBilEm 7 x 50 B/GA (iF) with a reticle.
NAVIDOC 7 x 50 B/GA (IF) nautical binoculars with reticle and compass.
As binoculars that have been designed specially for the nautical area of application,
the NAViDOC meets the requirements of yachtsmen and other water sportsmen.
The NAViDOC 7 x 50 is optionally available with integrated reticle and / or illuminable
compass. The slip-proof rubber coating and the absolutely water-tight casing turn the
NAViDOC into a reliable companion, especially for skippers, sailors and pilots.
A special lens coating protects against uV-radiation, absorbs distracting sun reflections
and increases contrast and brilliance.

Everytime it is necessary to get an accurate view of even the smallest detail from a great distance, the DOCTER®
ASPECTEm is indispensable. Experience unforgettable moments and plunge into the diversity and beauty of nature.
in particular wildlife observations are turned into a special experience with these observation binoculars.
Even the stars are brought within close reach by the ASPECTEm. Equipped with the impressive wide-angle eyepiece
(uWA), foreign galaxies are open to exploration.
The use of special ED lenses achieves an impressive contrast and absolute colour fidelity. The light aluminium body is
climate resistant, splash water-proof, highly weather-proof and dust-proof. Highly magnifying lenses necessitate the use
of tripods. The DOCTER®ASPECTEm is equipped with a standardised tripod connection so that it can be used with all
commercially available tripods. With that, you can provide your ASPECTEm with the right support for every application.

DOCTER®ASPECTEM 80/500 ED Eyepiece models
Standard eyepieceThe standard eyepiece is a universally usable eyepiece with an average magnification, a
large field of view and a good suitability for spectacle wearers. For DOCTER®, "standard"
is what others call "wide angle"!
Vario eyepieceEnjoy the possibility of gradually changing your ASPECTEm's magnification. Thus, you
can choose between a large field of vision or a particularly large magnification, enabling
you to optimally combine overview and detailed magnification. Due to its special paten-
ted design, this eyepiece counts among the few variable eyepieces, where the subjecti-
ve field of view is to a large extent independent of the set magnification. We are the only
manufacturer to offer variable eyepieces on observation binoculars.
UWA eyepieceThis ultra wide angle eyepiece constitutes a completely novel eyepiece with a state-of-
the-art design. Apart from the unrivalled panoramic impression, it is characterised by a
good monocular behaviour and its suitability for spectacle wearers due to the foldable
eye cup. in addition the uWA eyepiece is available in a special design as slip-on eyepi-
ece for astronomic applications. The ultra-wide angle anastigmatic eyepiece convinces
with its stigmatic (stigma = dot) imaging across the entire field of view. Thus, even stars
at the edge of the image are still visible as sharply defined dots in unparalleled precision.
