This is the newest Kowa binoculars to use the PROMINAR brand name, utilizing four XD lenses. These high performance binoculars use the technology of the TSN-880/770 series spotting scopes and pair XD lenses with convex lenses made of glass with special dispersion properties to reduce chromatic aberration to a further degree. This advanced technology creates a bright image with high contrast and remarkable colour reproduction that cannot be duplicated by a normal achromatic lens.
The prism is phase-coated to ensure sharp images and outstanding contrast.
New coatings provide superior image brightness and precise colour reproduction for improved viewing pleasure.
The diopter control is equipped with a locking mechanism that keeps the diopter from accidentally being changed
Kowa's roof prism binoculars use the Schmidt-Pechan prism. One surface of the Pechan prism does not provide total reflection, so we have applied a highly reflective multi-coating called C coating. This allows for a higher reflectivity than with silver or optically enhanced aluminium, offering a reflectance of 99% or higher across the entire visible spectrum (400 to 700 nm). Not only does this provide bright and sharp images, but accurate colour reproduction is also achieved. Furthermore, the roof prism of the Schmidt prism is phase coated to prevent the loss of contrast and image resolution.
C3 Multi-coatings provide precise colour definition and deliver optimal images.
Features Kowa's KR coating which protects the lenses from dirt and other foreign residue that may affix to the lenses during normal use. Even in cases where the lens is accidentally touched, fingerprints or oil can easily be removed through proper lens cleaning methods.
Phase coated roof prism ‒ The Schmidt prism roof surface is phase corrected to ensure sharp images and outstanding contrast.
Twist-up multi-step eyecups allow easy viewing even when wearing eyeglasses.
Kowa’s branded XD Lenses (eXtra-low Dispersion glass which has characteristics close to fluorite crystal), when combined with a concave lens possessing special dispersion properties, reduces a very high percentage of chromatic aberration (colour blur).
