Apochromatic Collimator Objective Lens Design with Big Field of View

Abstract:

Objective lens is the core part of a collimator, its quality has a direct impact on the collimators quality. Due to the small field of view and low image quality requirement, general collimator objective lens is difficult to achieve the requirement of testing an aerial camera s performance. So designing a large field of view, apochromatic collimator objective lens has an important practical significance. In this paper, the major qualifications were first proposed to design the collimator objective lens,according to which the initial configuration was confirmed. Then we used the ZEMAX optical design software to optimize the initial structure and normalized the optimized structural parameters. Finally the image quality of collimator objective lens was evaluated to make it achieve the requirement of qualifications.
