Zoom binoculars offer the user a range of magniﬁcations. The zoom function can be operated by

hand using a lever, or by switch when driven by a motor. Zoom systems vary by model.

Waterproof

binoculars and fog-proof binoculars should be nitrogen purged and O-ring sealed in order

for their internal lenses to be truly resistant to fogging and/or water damage.

Style of Binoculars – Porro or Roof Prism Design

Binoculars come in two distinct styles in which design is dependent upon the type of prism system

used. The image that passes through a binocular is upside down (a function of the lens) and needs to be

corrected. This prism is the optical glass inside a binocular whose purpose is to “invert” the image.

Roof Prism System: the prisms overlap closely allowing the

objective (front) lens to line up directly with the eyepieces.

The result is a slim, streamlined shape in which the lenses and

prisms that magnify and correct the image are in a straight line.
