Pelco : 13VDIR
Description
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 focus light energy on the same plane. The result is better focus, sharper contrast, and better overall image quality.
IR corrected lenses are particularly of benefit to Pelco’s day/night cameras, which “see” both 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.
Appropriate for indoor and outdoor lighting situations, the 13VDIR Series lenses will fit all 1/3-inch CS mount cameras requiring DC drive auto iris lenses. Lenses in the 13VDIR Series come with a standard square 4-pin plug installed for ease of installation and convenience.
Lenses in this series are available in 2.8X (13VDIR3-8.5), 3.9X (13VDIR2.8-11), and 6.7X (13VDIR7.5-50) zoom with varying focal lengths.
Maximum and minimum apertures for these lenses are f1.4 ~ f2.6 (13VDIR2.8-11), f1.0 ~ f1.6 (13VDIR3-8.5), and f1.3 ~ f1.8 (13VDIR7.5-50). This allows for excellent performance characteristics across a wide range of lighting conditions. These lenses have aspheric elements, which provide crisper, optimized images at all focal lengths.
