摘要
An athermalized and achromatized optical system (10, 30) has a lens group (12, 32) focusing energy on a focal plane (14, 42). The lens group (12, 32) includes at least two optical elements (22, 24, 26, 34, 36) of different material and a diffractive optical element (28, 40). The system (10, 30) enables athermalization and achromatization of the optical system.
