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.

"...Ophir optics, currently based in Wilmington, is moving to the ground floor of the North Building on the campus of the old Lucent Technologies plant at 1600 Osgood St.
Ozzy Properties President Orit Goldstein said Ophir's arrival sends a positive signal to other companies considering moving to Osgood Landing. 'We're very pleased that such a high-end and well established company such as Ophir Optics would move to our facility', Goldstein said."
