Jerusalem, Israel, Feb. 14, 2012 — Ophir Optronics Ltd. Announced that Armstrong Optical will represent the Infrared Optics Group of Ophir Optronics Ltd., a wholly owned subsidiary of Newport Inc., for the sales of its thermal imaging lens systems and optical imaging components.
The agreement, which is effective immediately, covers the UK and Ireland. Ophir Optronics anticipates it will help the company to penetrate the defense and security market in the UK, which it previously served through catalog houses or by itself from its offices in Jerusalem and Heerbrug, Switzerland.
The Infrared Optics Group manufactures and supplies optical lens assemblies for mid- and long-wave infrared, cooled and uncooled thermal imaging cameras, and infrared optical components and build-to-print elements and subassemblies for the defense, security and commercial thermal imaging sectors.
Armstrong Optical supplies systems for measurement, optical components, optomechanical assemblies, thermal imaging and thermography cameras, optical test instruments and complete lens systems for all wavebands.

Ophir Optics is introducing a state-of-the-art family of lenses compatible with the emerging next generation of uncooled focal plane arrays (FPAs). The pixel pitch size of these advanced FPAs has been reduced from 25µm to 17µm, consequently increasing the image magnification by 47% for the same optics when using the same number of pixels. The main challenge in designing lenses for such FPAs, is the fact that the small pitch size of 17um is not much larger than the IR wavelengths focused by the lens 8-12µm, or, in other words – near the diffraction limit. The smaller pixel configuration will dictate a lens with relatively low f/# and diffraction-limited performance that requires an optimum design together with tight manufacturing and assembly tolerances. Ophir’s family of 17µm compatible lenses will cover a wide range of applications, FOVs and FPA formats.
