Kowa TSN-99 PROMINAR Straight (TSN-99S)

A Kowa XD lens with extremely low dispersion characteristics is used for the convex lens of the TSN-99 PROMINAR. The concave lens paired with the fluorite crystal lens is made with special dispersion properties to reduce chromatic aberration even further.

This special combination virtually eliminates chromatic aberration even at high magnification. It redefines the standards of colour brilliance. This technology is the

result of many years of Kowa optical design.

• Highest resolution and transmission in class
• Most compact model in class despite having largest objective lens
• Weight either lighter or the same as smaller 95mm competitors
• Smoothest and most precise focussing
