Abstract

A reimaging lens assembly includes a pentaprismatic optic that includes two reflective surfaces and two refractive surfaces. The reflective surfaces are powered surfaces, and the reflective surfaces may be spherical, aspherical, and/or freeform reflective surfaces. The pentaprismatic optic may receive light from a wide field of view (WFOV), and may change the angle of the output light from that of the input light, for example by 90 degrees. The pentaprismatic optic may be coupled to an image receiver, such as a cooled or uncooled camera. The reimaging lens assembly may include further optical elements between the pentaprismatic optic and the image receiver, such as one or more lenses, filters, and/or cold stops. The lens assembly provides a compact system, with a small number of optical elements, and with desensitized output that reduces image jitter.
