About Us

A monocular is a modified refracting telescope used to magnify the images of distant objects by passing light through a series of lenses and usually prisms, the application of prisms resulting in a lightweight, compact telescope. Volume and weight are less than half those of binoculars of similar optical properties, making it easy to carry, and also proportionally less expensive.

Monoculars produce 2-dimensional images, while binoculars add perception of depth (3 dimensions), assuming one has binocular vision.     Monoculars are ideally suited to those with vision in only one eye, or where compactness and low weight are important (e.g. hiking). However, monoculars are sometimes preferred by those with normal vision, where using both eyes through binoculars causes difficulties.

    A monocular with a straight optical path is relatively long; prisms are normally used to fold the optical path to make an instrument which is much shorter (see the entr..
