    Abstract: The present invention relates to a light guide device (100) comprising light transfer frame (111), light guide cable (112), light directing slide (151), support means (120) and light positioning means (140) which is removably attachable to an imaging device such as a camera (10) with a lens (11) and a flash (12) to be used in dental imaging applications. Light transfer frame (111) houses light guide cable (112) so that it is aligned with flash (12) of the imaging device. Light emitted from flash (12) is transmitted to light positioning unit (141) of light positioning means (140) via optical fibers (131) encased in light guide cable (112). Distance of light positioning unit (141) from lens (11) is adjustable by light positioning adjustment unit (143). Light guide device (100) is securely and adjustably attached to camera (10) via support means (120). In some embodiments of the invention, polarizing filters (161 and 162) are placed in front of lens (11) and twin light sources (145) so that their polarizing direction is orthogonal to each other to obtain cross-polarized lighting. In this manner, the invention aims to provide a practical alternative for use in dental photography applications.
