Tamron Vari-Focal Lens Compatible with 4K/8-Mega-Pixel Resolution and NIR (Near-IR) Bandwidth

Tamron Co., Ltd. announced the market launch of a 4K/8 mega-pixel resolution 1/1.7” 3.8-17mm F/1.4 Standard Vari-Focal Lens (Model:M117VG3817IR) that delivers outstanding high-fidelity images over the entire visual and near-IR bandwidth spectrum.

The need for high-fidelity surveillance in 4K/8 mega-pixel resolution is growing in the surveillance camera market. In addition to high-fidelity, high-sensitivity is also a mandatory feature in a lens.

Tamron, addressing this growing market need, announces the release of a 1/1.7” 3.8-17 mm F/1.4 Vari-Focal Lens compatible with 4K/8-mega-pixel resolution, high-sensitivity, NIR- bandwidth, and CS-mount cameras. The new lens offers distinguished values in both high resolution and high sensitivity.

High Optical Performance Compatible with “4K/8 Mega-Pixel” Resolution

Use of an aspherical lens element, special LD (Low Dispersion) Glass Material, an XLD (eXtra Low Dispersion) lens element combined with state-of-the-art optics design technology assures unrivalled image fidelity compatible with 4K/8 mega-pixel and 5 mega-pixel cameras.

High Sensitivity Enhanced by F/1.4 Aperture

The F/1.4 wide aperture renders high sensitivity that enables night-time surveillance in 8 mega-pixel resolution.

Conformance to the Widely-Used Focal Length of 3.8 – 17mm with the Horizontal FOV (Field of View) Angle of 121.2°

High-fidelity 4K/8 mega-pixel resolution is provided over the most widely-utilized focal length range of 3.8 – 17mm^*. A wide-angle focal distance of 3.8mm supports a full range of high-fidelity imaging in outdoor installations.

* For 1/3”: Corresponds to the focal distance of 2.5 – 11.2mm

High-Fidelity 5-Mega-Pixel Resolution is Available, Even in the NIR Bandwidth

Integration of state-of-the-art optics design, choice of lens glass material, and enhanced engineering precision achieves outstanding improvement in CAS^* compensation, NIR performance, and corner resolution, resulting in unprecedented high-fidelity 5 mega-pixel resolution in the NIR bandwidth.

*CAS: Chromatic Aberration and Spherochromatism

Substantial Reduction in Chromatic Blur, Ghosting, and Flare

State-of-the-art optics design suppresses chromatic aberration to the bare minimum, rendering images without chromatic blur. Extensive use of advanced design and validation engineering eliminates unnecessary light reflection on the lens surface, while flare and ghosting are suppressed to the minimum by employing Tamron’s multi-coating technology.

Adoption of a Metal Mount for Higher Reliability

A newly adopted slip-mount mechanism assists the lens/camera integration for easy installation. Adoption of a metal mount achieves substantial improvement in reliability.

Tamron adds 5-55mm F/1.6 vari-focal lens with high resolution and NIR bandwith

Tamron announced the market launch of a Telephoto Vari-Focal Lens 1/2.7” 5-55mm F/1.6 (Model: M13VG555IR) compatible with mega-pixel resolution and NIR bandwidth.

Tamron has released a 1/3” 5-50mm F/1.6 lens (Model: M13VG550IR) for a wide variety of applications including city/street and traffic/vehicle surveillance. The current 5-50mm lens has enjoyed high valuation in the market as a standard Telephoto Vari-Focal lens with excellent high-fidelity and high-sensitivity. However, in the surveillance camera market, 1/3” and 1/2.8” imagers with consistent high-fidelity and high-sensitivity have become a de-facto standard, and a Vari-Focal lens that assures high-fidelity and high-sensitivity in both standard and telephoto ranges is a component mandatory for these imagers. Tamron addresses this need in the market by releasing a new 1/2.7” 5-55mm F/1.6 lens compatible with NIR bandwidth (Model:M13VG555IR).

1. High-Optical Performance Compatible with ‘Mega-Pixel’ Resolution Use of an aspherical lens element and special LD (Low Dispersion) glass material, combined with state-of-the-art optics design technology, assures unrivalled high-fidelity images compatible with mega-pixel cameras. The F/1.6 aperture assures mega-pixel resolution even under poor illumination.
2. NIR-Compatible Lens Covering a Wide Range of Focal-Length in Telephoto The new lens covers the commonly-used focal length of 5-55mm. In spite of a compact design, the focal length of 55mm is retained at the telephoto end.
3. High-Fidelity Imaging in NIR Bandwidth Integration of state-of-the-art optics design, choice of lens glass material, and enhanced engineering precision achieves outstanding improvement in CAS* compensation, NIR performance, and corner resolution, assuring high-fidelity mega-pixel lens performance in day-and-night surveillance. The mega-pixel resolution supported not only in the visible but also in the NIR bandwidth enables corner-to-corner crisp-and-clear imaging of targets even in the night-time when both visible and NIR lights co-exist.
   *CAS: Chromatic Aberration and Spherochromatism
4. Reduction of Ghosting and Flare Backlight performance is substantially improved by employing Tamron’s proprietary multi-coating technology. Use of state-of-the-art simulation and validation of use conditions in various security scenes effectively reduces ghosting and flare to the minimum.
5. Pursuit of Friendly User Utility and High Reliability in compliance with Tamron’s tradition of quality product development in pursuit of user utility and high reliability, the new lens also incorporates many of Tamron’s accumulated know-hows.
   ・Compactness designed to fit in a camera housing used in outdoor surveillance
   ・Large focus rotation angle for easier focusing adjustment
   ・Mount-slip mechanism to assist quick camera/lens integration in installation
   ・Employment of highly-reliable automatic iris mechanics
