An optical eye-contact element is disclosed that is at least partly translucent, the optical eye-contact element giving rise to a wavefront error of at most about &#x3bb;/2, preferentially at most about &#x3bb;/4, highly preferentially at most about &#x3bb;/10, in a traversing light beam. The optical eye-contact element may be a so-called applanation plate or applanation lens.

Eye-contact element

An apparatus and a method are presented for detecting the focal position of an optical system () with a radiation source (), a focusing imaging system (), an at least partially reflective surface () on the focus (), a digital camera () for recording an image reflected by said surface (), a computer (C) for evaluating the image recorded by the camera (), and with an optical element () in the beam path of the optical system () upstream of the focusing imaging system (), which element influences said image depending on the focal position.
