Abstract
Official abstract text for this publication.
An adaptor adapts an SLR camera for use as an ophthalmic viewing and imaging device. The adaptor is mounted to the camera between the camera body and the camera lens, and includes optical components arranged to direct illumination of the interior of the eye. The adaptor includes a first light source configured to provide a maximum level of illumination that is sufficient to identify structures of interest within an interior of an eye. The adaptor directs light from a second, external source to provide a level of illumination sufficient to obtain a fundus image. Optical components within the adaptor define a first optical pathway for directing light from the first light source to the lens, a second optical pathway for directing light from the second light source to the camera lens, and a third optical pathway for directing light from the camera lens through the adaptor to the camera.
First claim
Opening claim text (preview).
What is claimed is: 1. An adaptor configured to adapt a camera for use as an ophthalmic viewing and imaging device, the adaptor comprising a body including a first interface configured to connect to the camera so that an optical axis of the adaptor is aligned with an optical axis of the camera and a second interface configured to connect to a camera lens so that the optical axis of the adaptor is aligned with an optical axis of the camera lens, a first light source disposed with…
