Tamron Co., Ltd., an integrated optics manufacturer in the security/surveillance equipment industry, announces the release of a 3-mega-pixel 1/2.7” 2.7-13mm F/1.4 vari-focal lens (Model: M13VG2713IR) that supports high resolution throughout the visual and the near-IR spectrum.
Imagers are migrating toward higher resolution as high-quality images are required for security applications; high-end mega-pixel cameras are increasingly put to night-time surveillance use. Addressing the growing need in the market, Tamron developed an industry-leading high-resolution vari-focal lens that supports ultra-high resolution compatible with 3-mega-pixels throughout the visual light and the near-IR spectrum.
The new lens has the following features:
Distinguished optical performance
Leading technologies such as aspherical lens and extraordinary LD (Low Dispersion) lens are employed together with state-of-the-art optical design to achieve high-fidelity imaging compatible with 3-mega-pixel cameras, exceeding full HD1080P resolution. The lens boasts the fastest F-number; F/1.4, which effectively assures mega-pixel image quality even in low lighting conditions.
Mega-pixel imaging sustainable under IR lighting
The imaging quality of conventional lenses is often compromised under a near-IR light compared with that of a visual light. Image-quality degradation in the “night-time mode” devalues the advantage of mega-pixel cameras. The new lens maintains high-quality 3-mega-pixel imaging throughout the visual and near-IR spectrum, without quality degradation when a camera is switched to “night-mode”.
All lens components are designed with the highest precision and produced
Wide-utility focal length and wide-angle horizontal FOV angle
Mega-pixel image-quality is assured over the most widely-utilised focal-length range of 2.7 – 13mm. The focal length of 2.7mm at the wide-angle (FOV angle of 125.1°) is especially useful to obtain the view of an entire room from a corner point.
Reduction of colour blur by elimination of chromatic aberration
A new optical design eliminates chromatic aberration to the limit, resulting in images without annoying colour blur. Incoming light reflection on the lens surface is thoroughly suppressed by means of state-of-the-art lens design to prevent its incursion into output images. Employing multi-coating technology also assures flare-free and ghost-free imaging.
Highest-precision and highest-quality lens construction
All lens components are designed with the highest precision and produced using the most advanced manufacturing technology. In-house manufacturing know-hows are extensively employed to eliminate image degradation such as image shifts and unbalanced blurs in order to maximise optical performance.
Improved lens integration
Obtrusion of the lens element at the lens mount surface is eliminated to improve lens compatibility with general cameras.
