Development Concept

LWIR technology has earned attention in the security market in recent years for a number of applications, including monitoring of critical facilities and equipment. Tamron has won high praise for its launch of a high-function LWIR lens series as the first model of such a lens in 2012. LWIR technology works whether or not there is a light source and is largely immune to the weather and other conditions. As such, LWIR is starting to penetrate the market and receiving better recognition.

Optical zoom lenses make the most of detector performance, losing none of their picture quality while zooming. In the LWIR market, where fixed focal lenses are the norm, optical zoom systems offer a big advantage. While that is part of what prompted the expansion of the new system, there were also problems in adapting the technology in the existing equipment.

To address these problems, Tamron used its many years of technical experience to develop the world’s lightest optical 3X zoom lens. While the optical 3X zoom is the major feature of the product, with its light weight and compact form it can also match well with existing equipment. For more convenience, models are available with two types of front element coating, so that users can choose according to the housing type.

With its high performance, convenience, and the world’s lightest weight, Tamron will use LWIR 3X zoom lens for VGA(17 µm pixel pitch)detectors to expand the market.
