DEVICE FOR DETERMINING CENTRING PARAMETERS FOR THE ADJUSTMENT OF SPECTACLES

摘要

The invention relates to a device (10) for determining centring parameters for the adjustment of spectacles, the device comprising: a camera support (14) partially surrounding an inner area (22) that is open at the top, bottom and to the rear (30); and at least three cameras (16a, 16b) arranged between two free ends (18) of the camera support (14) and pointing towards the inner area (22), the camera support (14) having an illumination system (32, 34, 36) in order to illuminate the inner area (22). According to the invention, the illumination system (32, 34, 36) is designed to light the inner area (22) such that the light intensity, at least at each point in a region extending over a height of 20 cm and a central angle of 180 degrees of an outer cylinder surface having a diameter of 20cm and formed in the inner area (22), deviates by a maximum +50% and -30% from a predefined desired value.
