Zoom Lens

Characteristics & Mechanics of Zoom Lenses

Zoom lenses can accommodate a wide-range of magnifications by adjusting the distance between individual lenses within the zoom lens body.
These lenses allow for much faster observation in that the magnification can be quickly adjusted by simply rotating the zoom ring on the lens.
Since multiple objectives and a turret system are not needed, zoom lenses reduce the size and cost of the equipment.
