- Abstract
Continuous infrared zoom systems with image quality and image stabilisation maintained throughout the workflow are increasingly being used. A long-wave infrared continuous zoom optical system with a 6x zoom ratio operating with an uncooled detector was designed. The optical system has a focal length from 37,5 mm to 225 mm, and the F/# is 1,5. The system includes 7 lenses with 3 even aspheres. The results show that the MTF function is very close to the diffraction limit curve over the entire focal range, proving that the system meets the specifications.
