Tamron Co., Ltd., an integrated optics manufacturer and leader in the security\/surveillance equipment industry, announces the release of a 1\/1.8\u201d 12-50mm F\/1.4 5-mega-pixel NIR Vari-Focal Lens with P-Iris (Model: M118VP1250IR).<\/p>\n

Demand for IP\/network cameras is growing at an unprecedented speed in the security market. Today\u2019s requirement for high image-quality mandated resolution higher than 5-mega-pixel \/ Full HD 1080P.<\/p>\n

To address the market need, Tamron has released a \u2018Double Vari-Focal\u2019 lens system, a complementary lens-pair solution that powerfully supports major security applications: an M13VG288IR (f=2.8-8mm) lens and an M13VG550IR (f=5-50mm) lens to seamlessly cover the entire focal length range from the wide-angle f=2.8mm to the telephoto-end f=50mm. Because of the universal angular field of view coverage being addressed between the two, the solution has received exceptionally high recognition in the market.<\/p>\n

Demand for large-size 1\/1.8\u201d and 1\/2\u201d imagers has also grown prominently for surveillance installations in highly populated urban areas, where distinguished resolving power becomes critically important to make the most of the imaging capabilities of 5-megapixel sensors. To address the need, Tamron now releases a new 1\/1.8\u201d 12-50mm F\/1.4 lens, compatible with the widely-used P-Iris (Model: M118VP1250IR).<\/p>\n

Tamron, as an integrated optics manufacturer, progressively pursues development of such high-quality and innovative products.<\/p>\n

PRODUCT HIGHLIGHTS<\/strong><\/p>\n

1. NIR Lens Covering Focal Lengths Most Universally Utilized in Telephoto Applications<\/p>\n

The new lens delivers high-quality images throughout the most commonly used focal length range of 12-50mm. Expanding the spectrum coverage to NIR region, the lens enhances and assures high-precision and high-efficiency day-and-night surveillance.<\/p>\n

2. High-Quality NIR Imaging<\/p>\n

An ideal lens for day-and-night mega-pixel surveillance with chromatic aberrations well compensated for delivers improved performance in the NIR bandwidth and well-tuned image quality from corner to corner. Tamron\u2019s proprietary optical design with an optimal choice of glass materials backed by high-precision process technology brings an ideal balance in performance to cost.<\/p>\n

3. Discrete Optical Design Considering Low-Light Conditions<\/p>\n

The image circle diameter is expanded to permit compatibility with 1\/1.8\u201d imagers widely adopted in the security\/surveillance market. A fast aperture of F\/1.4 is achieved by a new optical design, while the minimum aperture stops down to close. The new lens is also compatible with 1\/2\u201d and 1\/3\u201d imagers.<\/p>\n

4. Substantial Reduction of Flare and Ghosting<\/p>\n

The performance of the new lens has gone through extensive validation processes using state-of-the-art simulation, weighed heavily on specific conditions of a wide variety of surveillance scenes. Disturbing flare and ghosting are attenuated to the minimum and Tamron\u2019s proprietary multi-coating technology is employed to thoroughly reducing flare and ghosting.<\/p>\n

5. Pursuit of High Utility and High Reliability<\/p>\n

In line with Tamron\u2019s product development philosophy for high reliability, proprietary knowledge and manufacturing know-hows have been extensively utilized for the design and manufacturing of the new lens, M118VG1250IR, similar with other Tamron products.<\/p>\n
