Paper Abstract

The development of focal plane technology in the production of very large linear arrays for infra-red sensors must be matched with optical systems capable of resolving up to 3000 pixels. Such systems have application in earth observation from space or airborne platforms. Radiometric rigour and stray radiation rejection are aided by the provision of an intermediate focus. The suggested optics can provide a flat image field and relative apertures to F/2 with a compact system of co-axial spherical optical surfaces. Although the design is for current detectors operating in the 3-5 μm infra-red window, the design is appropriate for the 8-13 pm window or dual band with alternative optical materials and surface coatings.
