ABSTRACT:
A lightweight telescopic lens of monolithic construction is revealed that corporates additional refractive and reflective curved surfaces to produce all the optical functions performed by an ordinary telescope. A pair of such lenses may be mounted in an eyeglass frame to yield a telescope that can be worn like a pair of eyeglasses, thus affording superior image stability as well as free the user's hands. Minor modifications involving the use of several menisci of a different index of refraction from that of the core lens can be made to achieve achromatism of emergent light from achromatic input light. The entire core lens can also be shaped into a meniscus to take advantage of the principle of total internal reflection, thereby increasing the light-gathering aperture while at the same time rendering the lens even more compact and lightweight.
