10-50mm CS-Mount, DC Auto Iris, 4K Varifocal Lens | SP1050MC8MPB

At SUPERIOR® Optical Center, Varifocal Lenses in Imaging Lenses provide a flexible solution to applications that previously would have required multiple fixed focal length lenses. Simply adjust the focal length to the desired field within the working distance range and then focus the lens for the best possible image. Varifocals are also called vari-focals, variable-focus or multi-focals due to their variable focal length range. Varifocal lenses can be set to a focal length in a specified range. Like zoom lenses, but unlike a zoom lens they also require focus adjustment after the focal length is selected. The optical and mechanical design is simpler, making them more cost-effective to manufacture than zoom lenses. The focal length adjustment is typically a middle or rear assembly of elements that slide back and forth, whereas the separate focus adjustment is typically a front cell movement.
