Description
Kowa Tsn-66 Prominar Spotting Scope: compact angled spotting scope with a 66 mm pure fluorite crystal lens, magnesium body and dual focus. 25-60x with TE-11WZ II.
Kowa’s Prominar scopes use pure fluorite crystal rather than ED glass in the objective, which nearly eliminates chromatic aberration (color fringing) on antlers and branches against a bright sky. The TSN-66 delivers that quality in a magnesium-alloy body Kowa positions as lightweight and portable, with dual (fast and fine) focus for quickly snapping onto an animal and then fine-tuning detail.

Who is the TSN-66 Prominar for?
Hunters and serious wildlife observers who want the most color-accurate image they can carry, and digiscopers who photograph animals through the scope.
What is fluorite crystal and why does it matter?
Fluorite has extremely low dispersion, so all colors of light focus at the same point. The result is a sharper, higher-contrast image with almost no purple or green fringing, most visible at high magnification.
Does the TSN-66 come with an eyepiece?
Kowa sells TSN bodies and eyepieces separately; the TE-11WZ II 25-60x zoom is the usual match. Email us to confirm which eyepiece is included in your order before you buy.
TSN-66 vs TSN-55
The TSN-55 is smaller and lighter (about 34 oz) with a 17-40x zoom; the TSN-66 gathers more light and reaches higher magnification.
