Samsung SLA-3580DN - CCTV lens - 3.5 mm - 8 mm

A varifocal lens allows the installer to adjust the field of view (zoom) to meet the needs of the application. Unlike a motorized zoom lens, a varifocal lens cannot be remotely adjusted. The advantage of the varifocal is that it is much lower cost than a zoom lens. The SLA series of varifocal lenses are high quality IR corrected auto iris lenses that are well suited for use with the high resolution Samsung Techwin cameras. The SLA-3580DN utilizes special low dispersion glass elements developed by Samsung Techwin specifically for Day & Night use. All of these lenses feature high optical performance without the ghosting or aberrations found in or binary varifocal lenses.
