EPOCH Lenses
All external lens surfaces have a Hard Coat
durability, and an anti-fog coating so inclement weather is never a problem.
Ocular lenses are hybrid aspheric for the least distortion of image and color.
The combination of Full-Multi coating on ocular lenses and Flat-light
transmission coated objective lenses work to yield near perfect image
transmission.
EPOCH Prisms
Unique SF prism material combined with next generation phase correction
coating, and AL-HR refl ective prism coatings complete a system with near
perfect light refl ectivity.
Prisms are secured with fi ve retention screws for extra impact resistance.
Eye Width Adjustment
EPOCH Body
The EPOCH offers a single hinge adjustment for fast eye width ad just ment,
a Magnesium Alloy body and grip-friendly armor coating making it incredibly
light and durable. In addition, the EPOCH is fully waterproof, dust-proof, and
fi lled with nitrogen to make interior fog-ups impossible.
Eye-width Adjustment
The distance between the center of the eye pupils is known as in ter p u pil lary
distance. Since everyone has a different interpupillary distance, the EPOCH
has a hinge which allows for eye width adjustment.
