About Kowa's Pure Fluorite Crystal Lenses...

Pure Fluorite crystal is the ultimate optical material because it virtually eliminated chromatic aberration in the visible light range.  The performance cannot be matched by an optical system composed of glass lenses, so why do other manufacturers very seldom use pure Fluorite crystal lenses.  Working with fluorite crystal material requires extra special care and sophisticated manufacturing processes.  Only a company with the experience and dedication to working with this unique material could produce an optical lens made of 100% pure Fluorite crystal!

Crafting the perfect optical system starts with meticulous hand polishing of the delicate lenses.  Each Fluorite lens is expertly shaped into a spherical surface and rigorous inspection follows to ensure quality before the next step, coating the lenses.

Optimal Coatings & Roof-Type Prism

Prominar lenses and prisms undergo advanced multi-layer coatings.  From countless combinations, engineers select the optical ones for peak performance.

Speaking of prisms, Prominar spotting scopes feature an advanced roof-type prism, which offers a linear optical path and compact design.

Lightweight Durable Spotting Scope Body 

Prominar spotting scope bodies are super durable yet lightweight.  Expert machine processing ensures precision shaping, while meticulous lens attachment and lubrication guarantee flawless performance.  Kowa's standard of quality include testing of each finished spotting scope to make sure it lives up to the Kowa Prominar name.  If it doesn't, then it won't go to market.  It's that simple.

Kowa Wide Angle TE-11WZ11 Zoom Eyepiece

Incorporated Into the design of the Kowa TSN-55 Spotting Scope is the 17x40 Zoom extra-low dispersion (ED) wide angle eyepiece.  Images are exceptionally sharp and detailed, elevating observation to new heights of clarity and precision.  Made in Japan, you'll experience a wide angle view that is stunning.

An eyepiece protection cap includes a strap that connects to the scope body on either side to help prevent the cap from getting lost.  You can remove the strap if you like, but it is nice to have installed, especially when you are in the field.
