Ikegami IK-12VG1040ASIR-SQ 10-40mm Day/Night Varifocal Lens

The IK-12VG1040ASIR-SQ is a 1/2-inch format C-mount lens with a 10-40mm varifocal range, built for day/night CCTV and factory automation cameras. The IR-corrected design holds focus as a true day/night camera switches between visible and infrared light, so the picture stays sharp around the clock. Set the field of view once and it covers a useful span, from a 37.5 by 27.5 degree wide angle out to 9.2 by 7.0 degrees at the long end.

A DC auto iris tracks changing light to protect exposure, while focus is set manually during install. The C-mount fits 1/2-inch box and cube cameras directly, and matches Ikegami bodies such as the ICD-49 and ICD-879S.
