Pelco 1/3" 13VDIR Series Day/Night Lens, 7.5-50mm

Pelco'nun 13VDIR Serisinin amacı, görünür ve IR ışığın farklı dalga boylarından kaynaklanan odak kaymasını telafi etmektir.

IR düzeltmeli lensler, ışık enerjisini aynı düzlemde odaklar. Sonuç, daha iyi odaklama, daha keskin kontrast ve daha iyi genel görüntü kalitesidir

Pelco 13VDIR7-5-50 | 7.5-50 mm (6.7X) Variable Focal Length | Direct Drive Auto Iris | CS-Mount | Format: 1/3" |
Iris Control: DC Auto Iris | Min Focal Length: 7.5 mm.

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. Maximum and minimum apertures for these lenses are 1.4-2.6 (13VDIR2.8-11), 1.0-1.6 (13VDIR3-8.5),
and 1.3-1.8 (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.
