摘要
A dual-band refractive optical system having an eyepiece-type arrangement and configured for mid-wave infrared and long-wave infrared operation. In one example the optical system includes a plurality of lenses, each constructed from a material that is optically transparent in the mid-wave infrared and long-wave infrared spectral bands. The lenses are arranged to receive infrared electromagnetic radiation in an operating waveband that includes at least a portion of the mid-wave infrared and at least a portion of the long-wave infrared spectral bands via a front external aperture stop and to focus the infrared electromagnetic radiation onto a rear image plane, the lenses being positioned between the front external aperture stop and rear image plane. The optical system can further include a corrector plate positioned coincident with the front aperture stop.
