Oasis Prism Coating
Oasis is the name given to a 64 layer coating process applied to the reflective surface of each roof prism. Oasis improves light emission to 99% over a broader spectrum at the reflective face when compared to silver coating traditionally used on many high quality roof prism binoculars. The result is a measurable increase in light transmission and overall image clarity.
PC Phase Correction Coating
When light waves are reflected at the opposite faces of a roof prism, phase shift occurs resulting in marginal deterioration in sharpness. Phase corrected coatings are designed to correct this phase shift within the prism – increasing overall clarity and definition.
