Delta Optical Chase ED Binoculars
Binoculars Delta Optical Chase is a model with universal parameters, perfectly adapted to the observations of nature and hunting. The size of the binoculars is a bit larger than in the models with 42 mm lenses, however, these binoculars are clearly lighter than the typical 10x50 binoculars, and their weight does not exceed 1 kg. The field of vision is large and equals 6.2◦, thanks to the use of comfortable wide-angle eyepieces with a comfortably extended exit pupil. Suitable for hunting, nature or tourist observations. Premium class binoculars with 50 mm ED glass lenses. With very low dispersion. The moderate dimensions and light weight combined with the high strength of the structure make it a recommended binocular for demanding users who spend time on difficult terrain.
· ED optics - perfect correction of chromatic aberration
· Wide-angle optical design with a completely flat field of view.
· BaK4 roof prisms with silver coatings and corrected phase.
· Fast, central diopter adjustment.
The carefully selected high quality glass grades and the newly designed optical system make the Delta Optical Chase series binoculars offer much better image quality than binoculars in a similar price class. All binoculars in this series were built with low dispersion ED glass lenses. Such lenses guarantee a low level of chromatic aberration while maintaining moderate dimensions. The binoculars have a large field of vision, corrected to a greater extent than in the models produced previously. The entire structure is made in a roof system with an internal central focusing system. The body is very resistant and, of course, completely impermeable. The binoculars of the Chase series will provide an image with very high details and rich colors, allowing you to see details that are not noticed in binoculars of lower quality.
