WIDE SPECTRUM OPTICAL SYSTEMS AND DEVICES IMPLEMENTING FIRST SURFACE MIRRORS

摘要

The present invention generally relates to wide spectrum optical systems and devices for use in multispectral imaging systems and applications and in particular, wide spectrum optical assemblies that are implemented using low cost, first surface mirrors in an optical framework that enables real-time viewing of an image in multiple spectral bands simultaneously over the same optical centerline with one main optical element.

主权项

1. An optical lens device, comprising:
a device housing comprising an input aperture and an output aperture; a primary first surface OAP (off-axis parabolic) mirror having a front reflective surface that reflects photonic radiation incident on the front surface, wherein the OAP mirror is fixedly positioned within the device housing such that the front reflective surface faces the input aperture and such that an optical centerline of the OAP mirror extends from the front reflective surface through the input aperture of the device housing, wherein the OAP mirror reflects incident photonic radiation directed along the optical centerline from a target scene to form a focused off-axis image of the target scene; and a coupling mechanism to removably attach the device housing of the optical lens device to an imaging device such that output aperture of the device housing is aligned to an input of the imaging device.
