BINOCULAR SPECIFICATION & TERMINOLOGY
01 | Magnification
The binocular magnification specification
is the first number in the binocular
description. e.g. a 10x42 binocular has a
magnification power of 10x. That is to say,
the viewed image will be 10x larger than
with the naked eye.
While a higher magnification will make
the image larger and easier to view it
will also reduce the field of view and
make any movement of the binoculars
more exaggerated.
Typically an 8 or 10x magnification power is
the preferred choice, but 12x magnification
is also available in some models.
02 | Objective Lens
The objective lenses are at the front end of
the binocular. The width of the objective
lens relates to the second number in the
binoculars description. e.g. a 10x42
binocular has a pair of objective lenses
that each measure 42mm in diameter.
Larger objective lenses give better light
transmission and allow for a brighter
picture. A larger objective lens will
allow the binoculars to be used in
lower light conditions.
03 | Field of View (FOV)
The width of the binocular’s view. A larger
FOV allows for a wider image to be seen.
This can be measured in terms of angle
(degrees), or by a set distance. e.g. the FOV
of the Frontier ED X 8x42 is 142m wide
when looking at an image 1000m away.
This is equivalent to 426ft wide when
looking at an image 1000yds away.

04 | Exit Pupil
The diameter of the viewing image when
the eye is positioned at the correct eye
relief. This is calculated by dividing the
objective lens diameter by the binocular
magnification. e.g. for a 10x42 binocular
we divide the objective lens diameter of
42mm by the magnification power of 10
to get 4.2mm.
06 | Eye Relief
The correct distance for the pupil to be
located from the ocular lens. When at this
distance the best viewing experience will
be achieved. All Hawke binoculars are fitted
with adjustable twist-up eye cups to help
gain the correct eye relief distance and
comfortable viewing experience.
(see page 9)
05 | Interpupillary Distance
The distance between the two ocular lenses.
This is measured from the middle of one
lens to the other. The interpupillary distance
has a range, as the distance will change
depending how open or closed
07 | Close Focus
The closest possible distance that
the binoculars can be focused at.
Binoculars with an ability to focus at
close range allow for better viewing of
nearby objects such as insects.

GLASS QUALITY & COATINGS
01 | Extra-low Dispersion (ED) Lenses
ED lenses are the most effective way to
improve image quality and stop colour
fringing (chromatic aberration). ED glass
allows for better concentration and
direction of light wavelengths, which give a
significantly sharper image and improved
contrast of colours and light.
02 | Apochromatic (APO) Lenses
An APO lens is built from multiple elements
to more tightly control multiple colour
wavelengths into one. This fur ther reduces
chromatic aberration and enhances
image quality.
03 | Fully Multi-Coated (FMC) Lens Coating
There are many lenses within a binoculars
optical system. Hawke’s FMC lenses ensure
that both sides of every lens have multiple
layers of coating which assist with light
transmission and help produce brighter
images with improved contrast.
04 | BAK-4 Roof Prism
BAK-4 is a type of glass used within the prism,
which is a system of glass elements inside the
binocular that ensure the viewed image is the
correct orientation after being magnified.
A roof prism is a more compact and sharper
version of older traditional Porro prisms.
05 | Phase Corrected Coating
The light traveling through a binocular
prism is reflected several times and as such
can lose its “phase”, meaning that colours
can appear overlapping and produce
colour fringing, also known as chromatic
aberration. A phase correction coating
helps to stop chromatic aberration.
06 | Silver Mirror Coating
A silver mirror coating can be applied to
elements within the prism and increase
reflection. This also improves brightness
and colour reproduction. The silver coatings
have a reflectivity of 95% to 98%.
07 | Dielectric Coating
Dielectric Coating of the prisms improves
internal reflection even more than a silver
mirror coating. This maximises the quality
of visible light and produces clear, highcontrast images, similar to those seen by
the naked eye.
08 | Water Repellent Coating
Water repellent coatings significantly
improve optical performance in wet
weather conditions. The extra lens coating
encourages the water droplets to “bead”
and form into smaller drops that are easier
to clean and will more actively run off the
glass lens.
09 | Strehl Ratio Tested
Meeting the Strehl Ratio optical parameter
ensures the image is crisp with no, or less,
haziness. This produces a feeling of not
actually looking through lenses.

PARTS & MECHANICAL FEATURES
01 | Dioptre
Each binocular is equipped with an
adjustable dioptre which is used to correct
any imbalance in eye strength. Typically the
dioptre adjuster is positioned on the right
hand eyepiece.
02 | Focus Wheel
The focus wheel can be easily rotated to
change the focal distance of the binoculars.
All Hawke binoculars feature a central focus
wheel which accurately guides and adjusts
the internal lenses while keeping them
protected from outside elements and dirt.
03 | Hinge Design
All Hawke models are adjustable at a
central hinge.
04 | Tripod Attachment
All Hawke full-sized binoculars have a tripod
fitting with a standard tripod thread (1/4-20
UNC). This allows for positioning and solid
mounting to keep the binoculars still when
in use
05 | Twist-Up Eye Cups.
With multiple height settings, the twist-up
eye cups can be set to ensure the best eye
relief for your use. Eyeglasses users often
leave the twist-up eye cups in the downward
position, while non-eyeglasses users rotate
the twist-up mechanism upright. The
Frontier models have the added feature
of replaceable twist-up eye cups with
position stops, allowing for the eye cups
to be replaced easily.
06 | Strap Loops
All Hawke binoculars are engineered with a
low-profile strap loop that provides a secure
attachment point for your beloved optics.
07 | Nitrogen Purged
Hawke binoculars are filled with nitrogen
gas to ensure that no condensation or
humidity is held within the optical system
which can otherwise haze and cloud
the optical view when moving between
warm and cold conditions. The nitrogen
gas is sealed into the binoculars during
manufacture to ensure no moisture can
infringe the optics.
08 | Chassis
Designed from conception to offer the
best performance available, models
include lightweight magnesium alloy
body or polycarbonate chassis and soft
touch rubbers.
09
FOCUSING YOUR
BINOCULAR
Set-up
Set the dioptre adjuster (01) to the
centre position.
Close your right eye and rotate the focusing
wheel (02) until the image in the left
eyepiece appears sharp.
Now close your left eye and rotate the
dioptre adjuster (01) until the image is sharp.
The binoculars have now been adjusted to
your eyes.

SPOTTING SCOPE SPECIFICATION & TERMINOLOGY
01 | Magnification
Spotting scope magnifications are often
variable as the zoom eyepiece allows
the user to change from low to high
magnification. The magnification range
is denoted by the first two numbers in
the spotting scope’s description.
e.g. a 20-60x85 spotting scope has a
magnification power of 20 to 60x.
That’s to say the viewed image will be
20 to 60x larger than with the naked eye,
depending on the magnification setting.
Whilst a higher magnification will make
the image larger and easier to view it
will also reduce the field of view and
make any movement and tracking of
animals more difficult.
02 | Objective Lens
The objective lens is the front lens of
the spotting scope. The width of the
objective lens relates to the last number
in the spotting scope’s description. e.g. a
20-60x85 spotting scope has an objective
lens that measures 85mm in diameter.
Larger objective lenses give better light
transmission and allow for a brighter picture.
A larger objective lens will allow the spotting
scope to be used in lower light conditions.
03 | Field of View (FOV)
The width of the spotting scope’s view.
A larger FOV allows for a wider image
to be seen.
This can be measured in terms of angle
(degrees), or by a set distance. e.g. the
FOV of a 20-60x85 spotting scope could
be 35 – 17.5m wide when looking at an
image 1000m away. The view is 35m wide
when on the lowest 20x magnification and
is 17.5m wide when on the highest 60x
magnification. This is also equivalent to
105 – 52.5ft wide when looking at an
image 1000yds away.

correct eye relief.
Some Hawke spotting scopes are fitted
with an adjustable twist-up eye cup to help
gain the correct eye relief distance and
comfortable viewing experience.
05 | Close Focus
The closest possible distance that the
spotting scope can be focused at. Spotting
scopes with an ability to focus at a nearer
range allow for better viewing of nearby
objects such as insects.

PARTS & MECHANICAL FEATURES
01 | Sunshade
When using the scope in bright conditions,
or when the sun is low and shining into the
spotting scope’s lens, the built-in extendable
sunshade can be used to prevent glare.
02 | Nitrogen Purged
Hawke spotting scopes are filled with
nitrogen gas to ensure that no condensation
or humidity is held within the optical system
which can otherwise haze and cloud the
optical view when moving between warm
and cold conditions. The nitrogen gas
is sealed into the spotting scope during
manufacture to ensure no moisture can
infringe the optics.
03 | Focus Wheel
The focus wheel can be easily rotated to
change the focal distance of the spotting
scope. All Hawke spotting scopes are
designed to accurately guide and adjust the
internal lenses while keeping them protected
from outside elements and dirt.
• Dual Focus Knob – a dual Focus Knob has
two sensitivities for adjustment; coarse
and fine. The coarse adjustment is fast
changing for quick settings, then the fine
adjustment allows for more accurate and
precise focus correction.
• Focus Knob – a single Focus Knob that
allows for adjustment from near to far
focal distance.
04 | Tripod Attachment
All Hawke spotting scopes have a tripod
fitting with a standard tripod thread
(1/4-20 UNC). This allows for positioning
and solid mounting to keep the spotting
scope still when in use. A rotating tripod band
is available on some models to allow body
rotation and alternative scope orientation.
05 | Eye Cup Adjustment
The eye cup can be set to ensure the best
eye relief for your use. Eyeglasses users
often leave the eye cup adjustment in the
downward position, while non-eyeglasses
users keep the eye cup upright.
• Twist-Up – with 3 levels of adjustment the
eye cup can be twisted into position to suit.
• Folding – the rubber eye cup can be
folded down to suit eyeglasses wearers.
06 | Digi-scoping
Digi-scoping is the art of using the spotting
scope’s optical performance to enhance
your camera and capture photos at a much
higher magnification. Digi-scope adaptors
are available to attach a camera to the
spotting scope.
