Product Summary
Pelco 13VDIR2.8-11 1/3" Varifocal Lens - Auto Iris The purpose of Pelco’s 13VDIR Series is to compensate for the focus shift that results from the different wavelengths of visible and IR light. IR corrected lenses allow a camera’s imager to take in visible and IR illumination in “night” conditions (when the IR cut filter is not deployed), while eliminating the problem of IR focus shift. |
