Biographical / Historical
Biographical / Historical
In the mid-1950s the Defense Department requested a system for achieving better quality photographic intelligence using smaller and lighter cameras on high-speed aircraft at high altitudes. In response Fairchild Camera and Instrument Corporation designed the KS-25 High Acuity Camera System, an integrated camera/lens system using a wide-angle 24' focal length lens capable of producing transparencies with resolutions of 140 lines/mm on a high contrast target or 90 lines/mm on a low contrast target. The lens for the KS-25 was designed by Dr. James G. Baker of Spica, Inc. and represented new optics technology to allow wide-angle viewing at daylight illumination on high speed cameras, yet capable of producing a resolution that was effectively diffraction limited.
