Abstract

An ophthalmic loupe for generating an aerial image of a portion of an eye is provided. The ophthalmic loupe includes at least one lens, which in turn includes at least one aspheric lens face. In combination with the remaining lens faces, the at least one aspheric lens face generates an aerial image of the portion of the eye with a field of view with a negative distortion in its outer region. In this case, the absolute value of the negative distortion at the edge of the field of view is larger than 15%.
