Non-reflective imaging optics for optical devices, particularly in opthalmology
Abstract:
Imaging optics for optical devices, with which reflections of the illumination light, which is guided through the same optical elements as the observation light, are kept from reaching the observation pupil of the imaging beam path. The non-reflective imaging optics include at least two refractive optical elements, which are utilized for illumination as well as observation. The at least two refractive optical elements are designed approximately wedge-shaped and are tilted at a random azimuth angle of at least 5° and/or are positioned off-center in the beam path to block out the single reflections of the illumination, occurring at the optical system surfaces, for the observation. The imaging optics are for optical devices, particularly in ophthalmology thought the invention is applicable to other ophthalmological devices as well as to optical devices outside of this field.
