Zoom & Variable Magnification Lenses

Zoom and Variable Magnification Lenses provide adjustable image magnification for imaging applications, from microscopy and life sciences to factory automation and inspection. These versatile lenses integrate seamlessly with cameras or imaging systems, enabling multiple magnifications without the need for complex recalibration.

Options include motorized zoom lenses with remote refocusing for consistent imaging in applications where manual adjustment isn’t practical, as well as zoom and variable magnification lenses that offer precise manual control for maximum flexibility and cost efficiency. High magnification, long working distance zoom lenses are also available, which are ideal for detailed inspection when space and working distance requirements are critical.

Edmund Optics offers a broad selection to meet diverse imaging needs, whether you require automated adjustment, manual control, or long working distances for demanding applications.
