Binoculars Opticron Oregon 4 PC Oasis 8x42 WP (30766)

When you need reliable binoculars with decent optical characteristics at an affordable price, Opticron Oregon 4 PC Oasis is one of the most suitable options. Like all high-quality Roof rotating prism binoculars, this model features phase-corrected prisms and the patented Oasis-C+ reflective coating. Despite the fact that the lenses use a standard achromatic gluing of lenses, the glass types are selected so carefully that the level of chromatic aberrations (color distortions) meets the standards of binoculars with low-dispersion ED glass lenses. The comfort of observation is also achieved due to the use of very wide 23.5 mm glasses, which provide a decent field of vision along the horizon and a minimum focusing distance of 2.3 meters.

Oasis Prism Coating is a proprietary 64-layer coating applied to the reflective surface of each Roof prism. Compared to cheaper silver coating (Ag coating) or budget aluminum coating (Al coating), it provides more than 99% light reflection from the surface in a wider spectrum, which provides a noticeable increase in brightness and clarity.

The assembly of Oregon 4 PC Oasis 8x42 WP binoculars, as is customary for all Opticron optical devices, is carried out at a high level and does not allow the smallest backlash of mechanical units. The binoculars are sealed according to the IPX7 class, which allows you to stay under water at a depth of 1 meter for up to 30 minutes without any damage to the optics, and the inside of the device is filled with inert nitrogen, which eliminates internal fogging and accumulation of condensate in the event of a sudden change in temperature.

The lens and eyepiece covers are made of soft rubber and fit tightly, additionally the lens covers are attached to the binocular tubes with rubber bands, which prevents their loss and allows you to use the binoculars quickly and efficiently. The neck strap is made of neoprene - a dense and soft hypoallergenic material that does not absorb moisture and is wear-resistant.
