Design of Infrared Optical System for Uncooled Thermographic Camera

ZEMAX optical design program was used to design, optimize and meet the targeted criterion of IR optical system which consists of 3 germanium lens and only one aspheric surface. 6061 aluminium alloy used to manufacture the mechanical case to assemble (carry and align) the optical system with thermal detector module and build simple handheld thermal camera. MATLAB computer software was used to create PC thermal image processing program in order to convert the thermal (gray) images to flash color images and read the object temperature from its image.
