Optical system for observing the interior of the eye and an ophthalmological contact glass for this

摘要

The non-reflecting ophthalmological contact glass (10), used in conjunction with an immersion, has a part of a semi-transparent ellipsoidal mirror (20) between the eye and the ophthalmoscopic lens or refractive surfaces, a light source or its image being arranged at a focal point (F1) lying laterally outside the contact glass (10) and the other focal point (F) lying in the pupil of the eye of the patient, so that the field observed is fully illuminated without, in this case, having mirror images. <IMAGE>
