20080291531 | Compact Objective Lens Assembly - A high-performance image-forming optical objective lens made compact and thin, particularly in the object side direction, by twice folding the optical path by means of two prism lenses longitudinally separated and arranged in an angular relationship to one another. The prisms have entrance and exit faces each of which is constructed of a curved surface having optical power, as well as having a rotationally symmetric polynomial aspheric attribute. The image-forming optical objective is particularly suited to helmet-mounted applications wherein the angular means for folding the optical path provides for an optical objective configuration that closely conforms to the exterior surface contour of the helmet, while providing a minimal forward projection in object space from the helmet. | 11-27-2008 |
20100208372 | Compact Objective Lens Assembly for Simultaneously Imaging Multiple Spectral Bands - An objective lens assembly suitable for use in helmet-mounted applications. The objective lens assembly comprises two prisms that collectively are configured, oriented and bonded relative to each other to separate and allow simultaneous imaging of two separate spectral bands (such as VNIR and LWIR bands) received from the same object scene via a common window such that the object scene may be viewed from the same perspective without the effects of parallax. | 08-19-2010 |
20110085242 | NEAR EYE DISPLAY PRISM OPTIC ASSEMBLY - An optical assembly uses a plastic prism with one flat surface and a collimating lens optic to provide the capability of imaging a color micro-display to the eye. The collimating optic and flat prism surface can allow for aberration-free diopter adjustment and an image with very low-magnitude, nearly-symmetric distortion. The collimating optic can also provide environmental protection of the prism involving an optical plastic device. The input illumination from the micro-display enters the prism, is reflected two times within the prism, exits the prism, and passes through the collimating optic before being viewed by the eye. Such an optical assembly can provide a field of view with eye-relief and exit pupil when viewing a full-color micro-display. | 04-14-2011 |
20130188056 | COMPACT OBJECTIVE LENS ASSEMBLY FOR SIMULTANEOUSLY IMAGING MULTIPLE SPECTRAL BANDS - An objective lens assembly suitable for use in helmet-mounted applications. The objective lens assembly comprises two prisms that collectively are configured, oriented and bonded relative to each other to separate and allow simultaneous imaging of two separate spectral bands (such as VNIR and LWIR bands) received from the same object scene via a common window such that the object scene may be viewed from the same perspective without the effects of parallax. | 07-25-2013 |
