Kowa Binoculars PROMINAR 10x33mm - Roof prisms binoculars
… Highest optical performance without chromatic aberration due to XD-lenses

Kowa Prominar 10x33 GENESIS

The PROMINAR 10x33 are high-end binoculars with true color imaging on the entire field of view. The optical technology of XD-lenses experienced in spotting scopes has been successfully passed to this binoculars. The result are absolutely outstanding binoculars.

Particularly the convincing exeptional brightness makes it possible to use the PROMINAR 10x33 at dawn and qualifies this item as outstanding night-binoculars.

Fields of Use:
-- Nature Observing / Birdwatching
-- Hunting / Safaris
-- Sailing
-- Astronomy


The PROMINAR XD-lenses
The XD33-10 have four PROMINAR XD-lenses. The paired convex lenses are made of glass with special dispersion properties to reduce chromatic aberration to a further, not distinguishable degree. This advanced technology creates a bright image with high contrast and outstanding color reproduction. The optical performance of the PROMINAR 10x33 cannot be duplicated or reached by a normal achromatic lens.

Highly reflective Roof Prisms
The new XD33 roof prisms provide a broad field and an enormous sharpness at the range with minimal lost of light.
The roof prism allows a nearly total reflectance which in combination with the Kowa C³ coating gives an absolutely outstanding viewing pleasure.

Phase-coated Roof Prisms
As a matter of course in this Performance class, the roof prisms are phase-coated to ensure sharp images and outstanding contrast.

Magnesium alloy body filled with nitrogen gas
The magnesium alloy body decreases the weight of the binocular while providing a rugged structure that can withstand the severest conditions. Self-evident that the glas is filled with nitrogen gas to prohibit inside fogging of the lenses.

Close focus down to 1.7 meters
The very short focusing of 1.7 meters makes the PROMINAR 33 as an excellent choice for a close range observation of plants, animals or insects.

Dioptre lock
The dioptre control is equipped with a locking mechanism that keeps the dioptre from accidentally being changed.

Kowa PROMINAR coatings

Kowa C³ coating
Kowa’s roof prism binoculars use the Schmidt-Pechan prism. Because the surface of the Pechan prism does not provide total reflection, Kowa applies a highly reflective multi-coating called C³-coating. This allows a higher grade of reflectivity than normal prisms with silver or aluminum coatings.

This coating gives a reflectance of 99% or higher across the entire visible spectrum (400 to 700 nm).
This not only provides bright and sharp images, but also an accurate color reproduction.
Furthermore, the roof surface of the Schmidt prism is phase coated to provide highest contrast and image resolution.
