Variable Focus Lenses: A-Series

Product Details

The A-58N Variable Focus Lens features a large aperture with large dynamic range and a low WFE (Typ. 0.1λ Max. 0.2λ), without compromising on the form factor or ease of integration

A-58N is based on Corning Varioptic’s breakthrough lens technology, allowing variable focus with absolutely no moving parts.

A-58N features 15 diopters of dynamic range, guaranteeing 7 cm focus ability and offers the same low power consumption, high shock resistance, and fast focus ability that have led to the success of the A-Series Variable Focus Lenses.

The lens is available with 3 different AR coating options, and in a packaged format with/without integrated thermistor.
