Wide angle optical design with fully flat field of view
Roof prisms made of BaK4 glass, with reflective layers made of silver
Quick, central diopter control

Carefully selected high quality glass grades and redesigned optics mean that Delta Optical Chase binoculars offer significantly better image quality than binoculars in a similar price class. All binoculars in this series are based on lenses made of ED glass with very low dispersion. These lenses guarantee a low level of chromatic aberration while maintaining a moderate size. Binoculars have a large field of view, corrected to a much greater extent than in previously produced models. The entire construction is made in a roof system, with an internal central focusing system. The body is very durable and of course completely waterproof. Chase binoculars will provide an image with very high detail and rich colors, allowing you to see details that are unnoticeable in binoculars of lower quality.

In rifle scopes, binoculars and spotting scopes ED (extra-low dispersion) glass (also sometimes referred to as a high density - HD - glass) is a high quality optical glass that increases light transmission, decreases light dispersion, and so cuts down on chromatic aberration, or "color fringing", which is due to the splitting of the light spectrum.
