Multi-Layer Lens Coatings: This basically means that the lenses have received multiple layers of anti-reflective coatings on all air-to-glass surfaces which increase light transmission to produce a brighter image and therefore better low light performance. Anti-reflective coatings can make a really big difference on the brightness of the image produced. It is not unusual to look through binoculars with smaller objective lenses, but with higher quality anti-reflection coatings and seen them outperform binoculars with much larger objective lenses, but with fewer or no coatings. The diagram above shows how these coatings improve the transmission of light.
Phase Correction: Phase correction is a set of coatings on the prism glass of roof prism binoculars that keeps light in correct color phases. These coatings are only needed on roof prism binoculars to enhance resolution, contrast, and color fidelity.
The top half of this image shows the benefits of phase correction.
BaK4 Prism’s: First - Prisms are what let you see a correctly oriented image when you look through a pair of binoculars. There are two types of prisms in common use, Porro prisms and Roof prisms. Roof Prisms as with the Alpen Shasta Ridge binoculars use BaK-4 prisms are the best in less expensive binoculars; they are made of superior optical glass that produces clearer images. These are what you want in your binoculars. BK-7 prisms are also used, usually in lower priced binoculars. These are satisfactory, but they are inferior to the BaK-4 prisms. Some manufacturers will not tell you what kind of prisms they use, usually because they are of inferior quality.
