Kowa objective

The PROMINAR XD-lenses
The XD44-8.5 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 8,5x44 cannot be duplicated or reached by a normal achromatic lens.

Highly reflective Roof Prisms
The new DX44 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.

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.
