Abstract

An 8 element refractive lens of 324.4 mm EFL and f/4.5 was designed for the spectral band 520nm to 590nm. The FOV of the lens was +- 5 degrees. The computed MTF of this lens system was better than 0.7 for spatial frequencies up to 60 1p/mm, as against the diffraction limited MTF of 0.81. A similar lens was designed for the spectral band 770nm to 860nm. These two lenses will be configured alongwith a panchromatic catadioptric lens of 900 mm EFL for high resolution spacecraft remote sensing applications. The design details of these lenses were presented in this paper.
