Extremely portable, these binoculars are suitable for numerous applications, including sporting events, hiking, traveling, and bird watching.

 



The prism is phase-coated to ensure sharp images and outstanding contrast.


All lenses and prisms are fully multicoated, ensuring a clear visual range and sharp images.


This new coating technology maximizes the reflectivity of the prism and reduces the loss of light, thereby achieving brighter and sharper images.


Ideal for observation of plants, insects, and other objects within close range.


*Not intended for use underwater.



Kowafs 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 aluminum, 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 color reproduction is also achieved. Furthermore, the roof prism of the Schmidt prism is phase coated to prevent the loss of contrast and image resolution.
