Abstract
An optical combination includes an input lens having an optical axis for receiving incoming rays, an output Petzval lens combination including spaced apart doublet lenses Land Lboth aligned along the optical axis, and an acousto-optic tunable filter (AOTF) that defines an input side and an output side for the optical combination positioned between the input lens and L. An input aperture stop is on the input side and an output beam stop is on or near L. The input lens can be an input Petzval lens combination including spaced apart doublet lenses Land L, wherein the input aperture stop is on or near L, and the input Petzval lens combination and output Petzval lens combinations are aligned back-to-back.
