Miniature telescopes of both Galilean and astronomical design are fashioned to allow bi-level viewing, simultaneously, of both magnified scope images and non magnified normal images of both far and near objects or areas. Improvements in bi-leveling telescopes involve: objective lens aspherics, ocular lens materials of high refractive indices, anti-reflective fabric like materials for internal light control. This combination of innovations results in a bi-levelable miniature telemicroscope displaying wider magnified fields which display brighter and clearer imagery. Peripheral chromatic and spherical aberrations are considerably reduced even in shorter length telescope units. These shorter length scopes are spectacle mounted in such a way that the front surface of a spectacle carrier lens is coplanar with the telescope objective lens. Tintings and other coatings can now be applied to any of the scope's lenses or internal disks as well as to spectacle carrier lenses.
