Optivisor Pro-Headband Magnifier

Description

Precision Optivisor binocular magnifier keeps both hands free

The Optivisor Pro-Headband Magnifier meets the demands of professionals in science labs, craft studios, production lines and engineering workshops for a hardy system of interchangeable lenses for close-up, hands-free work. It comprises a lightweight, adjustable headband with padded orthopaedic felt inner for comfort, and a tough, pull-down plastic lens visor. The visor can hold a selection of different-strength prismatic optical glass lenses, to magnify near-view components, objects and text. The lenses are mounted on the front in a plastic frame and can easily be removed and replaced with other lenses offering different magnifications.

Tilting lens at your fingertips

The Optivisor can be worn over normal prescription or safety eyeglasses and pivots up and out of the way when not required, enabling the user to quickly alternate between normal vision and extra magnification. The interchangeable lenses are ground and polished to precision optical standards and go up in half sizes from 1.5x to 3.5x magnification, with working focal lengths ranging from 20 inches down to just 4″. As an example, lens code DA4 magnifies two times (2x) at a working distance of about 10″/25cm.

Extra magnification – single eye lens

If even more magnification is required an auxiliary single-eye round lens adds a further 2.5x magnification over and above the figures shown below. The standard Optivisor comes with the popular 2.5x lens plate already included. Other lenses can be purchased as separate add-ons.
