Delta Optical Chase 12x50 Binoculars are a model with universal parameters, perfectly suited for both nature observation and hunting. The size of the binoculars is slightly larger than that of models with a 450 mm lens, but they are significantly lighter than typical 12x50 binoculars and weigh no more than 890 g. The field of view is large at 5.3°, thanks to the use of comfortable wide-angle eyepieces with a conveniently offset output pupil. Versatile roof construction suitable for hunting, nature and tourism observation. Premium binoculars, with 50 mm lenses made of ED glass with very low dispersion. Their modest size and light weight combined with their high strength make them recommended for demanding users spending time in difficult terrain.

Ed optics - perfect correction of chromatic aberration
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 adjustment

Carefully selected high quality glass grades and redesigned optics make Delta Optical Chase binoculars offer a much 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.
