Prominar optics for the TSN-88/99 models

The TSN-66 utilises optical solutions originally developed for Kowa’s larger TSN-88 and TSN-99 models. The fluorite crystal lens and improved coating allow light to pass through efficiently across the entire visible spectrum, and the image is reproduced without chromatic aberration. The KR coating on the front lens repels dirt, moisture and dust.

Dual focus for quick and precise adjustment

With quick focus, the subject comes into focus in just a few turns, and with fine focus, you can fine-tune the focus with your fingertip. The focus works from 3.5 metres, so you can even focus on subjects that are quite close by.

Compatible with Kowa System accessories

The accessory mount and bayonet mount are fully compatible with the entire Kowa System range of accessories. The TSN-66 is also available as an angled eyepiece, the TSN-66A.
