How you choose and equip a predator hunting rifle affects where its bullets go, and whether you can tap the rifle's potential when you're in the field. (Photo: Wayne van Zwoll)
Optical glass is of many types, specified by scope-makers that buy it and then grind and polish it into lenses.
Using a “fine milling” process that has replaced traditional grinding, the Zeiss shop can produce a lens in about two minutes. But polishing, with diamond paste as the common cutting agent, takes up to eight hours. Tolerances of 0.0001 mm defy mechanical measure; lenses and prisms are gauged with lasers and reflected light.
Clean prisms, when pressed together, adhere by vacuum! In the technology industry, such precision yields semiconductors with tolerances 4,000 times finer than the diameter of a human hair.
Coating follows for lenses. MeoBright lenses in Meopta’s fine Czech-built scopes have 13 coatings, applied in eight coating machines that cost more than a million Euros each!
Quality shows in a scope’s images, adjustments and durability. Shop accordingly based on your preferred hunting or shooting situations.
