The straight TSN-88S 88mm PROMINAR Pure Fluorite Spotting Scope from Kowa is a world-class spotter that redefines the standards of color brilliance, sharpness, and brightness. The TSN-88S uses an element of pure fluorite crystal (PFC) glass in its construction, which greatly minimizes chromatic aberration. This ensures maximum efficiency in its light gathering, producing a clear visual range and sharp imagery that traditional glass lenses cannot attain at their highest magnifications and with the strongest of subject/background contrast changes. The housing is made of a magnesium alloy that defines maximum durability and lightweight construction, resulting is a compact, ergonomic, and functional design for extreme nature and outdoor enthusiasts. An eyepiece is not included and sold separately.

Fluorite crystal lenses makes for the ideal lens material with ultra low dispersion properties not possessed by an ordinary optical glass. This outstanding specification adds the featured benefit of a near-completely reduced chromatic aberration, or color blur, to provide users with the ultimate viewing experience.

A dual tripod mounting screw allows the scope to be safely secured to both 1/4 and 3/8" mount.

Kowa's standard eyepiece bayonet mount includes a locking mechanism to prevent the eyepiece from getting lost or falling out unexpectedly. An eyepiece is sold separately.

The magnesium alloy body and barrel is constructed by a sophisticated process called thixotropic molding to give the strength and feel from a traditional metal body but with much lighter weight. The rugged structure can tolerate the severest conditions and deliver the highest level of confidence and security.

Kowa's focus system has progressed to a dual focus system with smooth movement at high magnification for pinpoint accuracy in image display. The quick focus can easily shift from infinity to 16 feet in two revolutions with the large and maneuverable knob. The fine focus moves fluidly to create pinpoint accuracy and is extremely useful at high magnifications and with digiscoping systems.

The housing is waterproof to JIS Protection Class 7 and filled with dry nitrogen gas to prevent internal fogging to ensure images clarity.

THERE IS NO GREATER EXAMPLE OF COLOR THAN THAT OF THE NATURAL WORLD.
A vibrancy when witnessed that can stir our emotions and make us feel alive.

Seeing nature represented true to life can be one of the most engaging experiences we can ever hope to enjoy.

For decades, it has been the passion, drive and goal of Kowa optical engineers to always deliver this natural spectacle to the observer in glorious detail through our optics.

IMPROVING AN ICONIC OPTIC.
When crafting the new TSN-88 PROMINAR series, Kowa went back to its roots in optical design.

Roots which have made it one of the most popular spotting scope manufacturers in the world.

To enhance a basic fundamental feature that PROMINAR users enjoy every time they look through their eyepiece - Natural Color.

Kowa has always prided itself on manufacturing optics that deliver a pure rendition of the view in front of the lens. Allowing you, the observer to explore and enjoy every detail of the subject.

An image free of negative optical distractions allowing you to immerse yourself into the scene in front of you.

GETTING BACK TO BASICS.
So, how exactly do you improve on an optic that has for almost two decades been at the forefront of optical innovation? The answer was clear, how the scope interacts with light.

Kowa engineers have improved the unique optical coatings applied not only to the lenses but also the prism in the new TSN-88 PROMINAR spotting scope series.

The result is a spotting scope that delivers even higher levels of light wavelength transmission than its predecessor and most important of all, across the entire color spectrum.

MEET THE NEW 88MM FLAGSHIP PROMINAR SPOTTING SCOPE.
UNDERSTANDING LIGHT.

Available light enters through the objective lens and internal optics of the spotting scope which is then finally transmitted to our eyes via the exit pupil. The more light photons that make it through the lens, the better and more clear we can see the object at high magnification and in greater detail.

Lens coatings help to transmit the light photons entering the optic and control how the image is delivered to our eyes.

Lens coating chemicals which are not perfectly balanced with high performance across the entire color spectrum can produce unnatural colors in the final image seen by your eye.

Cool or blue tints, or possible warm or red tints are often associated with optics that have good transmission values in certain wavelengths of light – but not the full spectrum.

NEW OPTICAL COATINGS ARE ONLY HALF THE STORY.
The new TSN-88 PROMINAR series features an 88mm pure fl uorite crystal objective lens - the true optical
powerhouse at the heart of all PROMINAR fl agship optics.

ELIMINATING CHROMATIC ABERRATION
Chromatic aberration occurs due to the dispersion of light and the diff erent wavelengths of light focusing on diff erent positions, resulting in a red or purple fringing around the image. Aligning these light wavelengths in to one focal point is critical.

Th e optimum optical material to do the job and minimize chromatic aberration is fl uorite crystal

ULTIMATE CONTROL.

DUAL FOCUS
The dual focus system is one of the defining features of our flagship spotting scopes, highly engineered to give ultimate control, the TSN-88 PROMINAR is no exception, the optic is a dream to use out in the field.

The dual focus mechanism is the gateway to controlling the image between your eye and the scope. Exquisite engineering is refined to make operation flawless. Quick focus allows for fast action to bring your subject in to detail in just a few smooth revolutions, whilst Fine focus gives pin-point, finger-tip control offering the ultimate in focussing accuracy with minute adjustments possible even when wearing gloves.

We believe no other spotting scope offers this level of fine control.

The responsive focus system is tuned to not only respond effortlessly for conventional observation, but increases performance for applications such as digiscoping when accurate focus is critical.

WE DIDN’T REINVENT THE WHEEL.
When we developed TSN-88 PROMINAR we had the benefit of experience behind us.

We utilized and enhanced the key features that have made our flagship PROMINAR optics range so popular with nature viewers around the globe.

SUN SHADE
A smooth twist sunshade helps to eliminate glare from the sun and also reduces exposure of the objective lens to elements such as moisture, grit and sand.

ACCESSORY COLLAR
An easy accessible collar on the eyepiece mount allows for quick connection of current KOWA SYSTEM accessories including adapters for digiscoping and 1.6x extender.
This accessory collar is the gateway to expand the scope to new levels of functionality.

EYEPIECE RELEASE BUTTON
To release the eyepiece smoothly, we re-engineered our quick release button, further enhancing the operation to allow quick eyepiece or adapter changes without compromising on a secure connection to the scope body.

DUAL TRIPOD MOUNT
The tripod mount features a dual mounting system which helps prevent the scope from slipping or rotating on the tripod shoe ensuring extra stability for long periods of use.
The tripod mount has removable screws that allows the spotting scope to be attached to either 1/4 and 3/8 inch tripod heads. With the tripod screw inserted the mount can be used on 1/4 inch tripods. Removing the screw allows the scope to be attached to 3/8 inch tripods.
The orientation of the scope can be smoothly changed with the release of a locking button if you require to alter the viewing position.

FILTER THREAD
A 95mm filter thread is situated on the scope body allowing for a protective or UV filter to be added offering enhanced protection.
The sunshade can still be used even with a filter added.

AIMING SIGHT
The spotting scope includes a new detachable aiming site that can be fixed on to the accessory collar to assist in locating your subject more rapidly.
The lens hood also features a newly designed built in aiming site as a further visual aid.
