The Large exit pupil provides bright images and ease of viewing and all lenses are made of environment friendly eco-glass. The use of magnesium alloy increases durability while reducing weight.

The inner focus system decreases image movement when focusing with the ability to focus from 5m to infinity in two revolutions of the quick focus knob. An eyepiece locking mechanism prevents the eyepiece from falling out or being lost.

The advanced lens system of the TSN-880 Series allows for a compact size and achieves less chromatic aberration without compromising brightness. Little to no chromatic aberration; even at higher magnifications is detectable and new lens coatings increase the light transmission ratio, providing brighter and more natural viewing.

The Rugged and durable metal body is fully Waterproof and nitrogen purged to prevent the lens from fogging and a Tripod mount with insert, in the body, allows the use of 1/4" or 3/8" tripods.
