Tamron develops two mega-pixel / IR-corrected 1/3" - format vari-focal lenses

Product Profile

Tamron Co., Ltd. recently announced the development of two 1/3"-format 2.8-8mm F/1.2 Vari-Focal lenses (Models M13VM288IR / M13VG288IR) that are compatible with 3-Mega-pixel-Day / Night cameras and deliver full high-definition 1080p images over the entire focal length range, both in visible and near-infrared light ranges.

The development concept

As a result of the rising demand for higher image quality in security systems, requirements for higher pixel sensors are increasing. In addition to this trend, the demand for Mega-pixel Day / Night cameras for night time surveillance is also increasing. To meet the trends and needs of the market, Tamron engineers challenged themselves to expand the specifications of Mega -pixel camera lenses and have successfully developed two new, state-of-the-art Vari-Focal lenses that are compatible with even 3-Mega-pixel-resolution systems and at the same time correcting the shift in focus for the Day / Night function.

Main features

  • High performance 3 Mega-Pixel Lenses
  • Accomplished Mega-Pixel resolution even in "Night Mode"
  • 100 degree horizontal angle, Super-wide-angle lens
  • Clear images without colour smear by minimising chromatic aberration
  • Highly accurate mechanical construction derives the highest performance from the advanced optical design
  • Mega-pixel-compatible performance, yet compact like conventional models
  • Designed to match the new camera technology
