Tamron announces development of LWIR 3X compact and lightweight t zoom lens
Tamron today announces a prototype LWIR (Long-Wave Infrared) 3X zoom lens, 35-105mm F/1.6 (Model #SC001) designed for VGA resolution FPA (Focal Plane Array) with 17㎛ pixel pitch in a compact and lightweight lens design. The lens covers a versatile focal length range of 35-105mm, equivalent to approximately 110-330mm in 35mm film format, with a constant maximum aperture of F/1.6 throughout the entire range. The lens provides excellent illumination characteristics from center to corner and incident angle to FPA optimally designed to minimize any adverse influence on shading to make the most of the 640 x 480 or 640 x 512 pixel arrays.
This is the third LWIR zoom lens from Tamron following the currently available 15-45mm F/1.4 and 35-105mm F/1.0 lenses that featured VC (Vibration Compensation), and is positioned to expand the horizon of indoor and outdoor surveillance applications for the security industry. The lens comes with two types of coating on the front of the housing coupled with IP67-compliant construction; and the other with AR coating for indoor applications. The new 3X is scheduled to be in production toward the end of 2013.
