The Kowa Spotting Scope TSN-99S Prominar is the new flagship of Kowa.
The TSN-99S is equipped with a large 99mm pure fluorite crystal
objective lens, which in combination with a Kowa XD lens delivers
superior performance in low light. This special combination, combined
with the improved optical coatings, virtually eliminates chromatic
aberration, even at high magnifications. Because the TSN-99S is equipped
with a dual focus mechanism, the image can be focused faster and more
accurately in just a few smooth revolutions. The fine focus mechanism
provides the final control to view the image razor sharp.
Because the Kowa TSN-99S uses a 100% magnesium alloy, it is a compact
and lightweight spotting scope in its class. The TSN-99S is easy to
carry and has a fully waterproof and nitrogen sealed housing with Kowa
KR coating on the optics. This makes the binoculars reliably robust.
Kowa TSN-99S with TE-11WZ II WA eyepiece
This kit comes with the Kowa TE-11WZ II wide angle eyepiece. This
eyepiece has a magnification of 30x-70x and features two XD lenses, so
the images are displayed with excellent sharpness. The eyepiece is fully
waterproof and features a Twist-up eyepiece ring with three positions.
This allows you to adjust the distance between your eye and the
eyepiece. In this way, both spectacle wearers and non-glasses wearers
have a pleasant viewing experience.
"Prominar" Lens
Chromatic aberration occurs due to the diffusion of light and the
different wavelengths of light that concentrate at different positions,
which can result in a red or purple border around the subject. The
optimal optical material to minimize chromatic aberration is Fluorite
Crystal. For the convex lens of the TSN-99A/99S, a Fluorite Crystal with
extremely low dispersion characteristics is used. Instead of an
ordinary optical glass lens, the hollow lens in combination with the
Fluorite Crystal lens is made of glass with special dispersive
properties to further reduce chromatic aberration. This combination
virtually eliminates chromatic aberration and redefines the standards
for color brilliance.
Fluorite crystal is only used in the top models of Kowa.
Key features Kowa TSN-99S Prominar:
Large 99mm fluorite crystal lens The fluorite used as an optical lens is an artificially grown
monocrystal with "ultra-low dispersion", a property that ordinary
optical glass does not have. It is an ideal lens material that almost
completely eliminates chromatic aberration (colour blurring). The
fluorite crystal produced by the advanced processing technology Kowa has
built up over the years guarantees the ultimate viewing experience. Dual focus mechanism (Quick and fine focusing) Eyepiece lock mechanism Strong, lightweight and portable Designed for digiscoping
100% compatible with the KOWA SYSTEM. Easily change eyepieces,
accessories and use digiscoping adapters for DSLR cameras and
smartphones. Create a truly flexible optical instrument for many
applications.

Eyepieces
An eyepiece should not be missing when purchasing a Spotting Scope.
Without an eyepiece you can't see anything. Below is an overview of the
eyepieces that fit the TSN-99S with the corresponding specifications:

Extender
When a Kowa TSN-EX16 extender
is placed between the Kowa TSN-99S and the eyepiece, the magnification
is increased by as much as 1.6 times. In combination with the TE-11WZ
eyepiece, a magnification of 40-96x can now be achieved.
Astro Adapters
With the use of a Kowa Astronomy adapter, the TSN-99S can also be
used for night-time celestial observation and photography. For this
purpose a universal 1.25" astro eyepiece can be used.
Two variants are available; the
TSN-AS1.25K has knurled screws with which eyepieces can be tightened by
hand. This allows you to quickly change eyepieces. The TSN-AS1.25G is
supplied with an Allen key. The advantage is that there are no
protruding screws visible.
Digiscoping Adapter
It is also possible to use your Kowa TSN-99S as a powerful
telephoto lens in combination with your DSLR or system camera or even in
combination with your smartphone. In this way you will be able to
capture the most detailed and vivid photos of subjects you would
otherwise not be able to get close enough to.
TSN-PA7A
By using the TSN-PA7A, you
connect the TSN-99S directly to your DSLR camera by means of an optional
T2 ring. This creates a powerful yet lightweight and compact telephoto
lens compared to traditional telephoto lenses.
TSN-DA10
The TSN-DA10 is perfect for
the compact and lightweight Micro Four Thirds cameras. Using the
TSN-DA10 and an optional adapter ring, everything is ready for use
within a minute. The optional adapter ring is available in various
sizes, depending on the filter size of your lens:
AR28/30/30.5/37/43/46/52/55/58/62/72mm.
Smartphone Adapters
If you would like to make
photo and video recordings with your smartphone, this can be done by
using a Kowa Smartphone adapter which is specially made for your
smartphone. This smartphone adapter is a protective cover that can
remain in place around your smartphone and offers protection against
falls and knocks.
Protective equipment
To protect your valuable Kowa TSN-99S, you can choose to complete it with the accessories listed below:
Kowa C-992 water-repellent Stay-On Bag Kowa TSN-CV88 Eyepiece protector Kowa TP-105FT Protective filter
Damage to the objective lens can drastically reduce optical
performance, which also causes costly repairs. Precisely because the
TSN-99S is equipped with a lens made of pure fluorite crystal. Often,
the only option left is to completely replace the entire lens.That is
why using protection is advisable.
