The unique optical design assures optimal performance with HD Megapixel camera applications and is available in Manual, DC Auto-Iris, and P-Iris models. Purple Fringe Correction Precisely engineering the lens elements and the unique optical design eliminates the chromatic aberration known as “Purple Fringe” - especially in strong backlight situations. 3 Megapixel Varifocal Designed to capture precise detail in critical security applications. High-quality optics maximize performance with 3-megapixel camera sensors. Full HD Format By enlarging the image circle design, this series is fully compatible with 720p and 1080p 16:9 format image sensors and the standard format 4:3 sensors. Precise Focus Adjustment The focus mechanism has been redesigned to allow more precise focus control. The focus ring rotates a full 180 degrees, allowing enhanced fine-tuning. IR Corrected Optics Designed specifically for true day/night cameras to deliver HD Megapixel resolution in both day and night modes even when IR illumination up to 950 nm is deployed. Corner Brightness The advanced optical design provides for exceptional brightness in the corners of the image, enhancing overall picture quality and sharpness throughout the image plane.A4Z1214CS-MPIR Technical Specifications: Product Line / Series 3 MP Series Lens Type Variable Focal Length IP Rating Not Specified Focal Length 12.5 - 50 mm ƒ/N ƒ/1.4 - ƒ/16 Image Circle Diameter 6.6 mm Image Size Dimensions 3.2 mm x 5.8 mm Imager Format 1/2.7″ Light Spectrum Visible, NIR Resolution (MP) 3 Resolution (Pixel Size) Not Specified Weight 80 Mount CS-Mount Filter Thread M40.5-0.5 Minimum Object Distance 1000 mm Magnification Not Specified Depth Of Field Not Specified Front Diameter 21.7 mm Rear Effective Diameter 9.1 mm Focus Control Manual Iris Control Manual Zoom Control Manual Focus Range 1 m - ∞ Back Focal Length 7.3 mm Zoom Range 12.5 mm - 50 mm Operating Temperature Range -10 to +50 °C Dimensions 49 × 49 × 58.2 mm AOV @ 1/2.7″ (16:9) H°×V°×D° 26.3 × 14.5 × 30.3° 6.7 × 3.8 × 7.7° AOV @ 1/2.7″ (4:3) H°×V°×D° 24.0 × 17.8 × 30.3° 6.2 × 4.7 × 7.7° AOV @ 1/3″ (4:3) H°×V°×D° 21.7 × 16.2 × 27.4° 5.6 × 4.3 × 7.0°
