PCT No. PCT/DE96/00093 Sec. 371 Date Dec. 10, 1996 Sec. 102(e) Date Dec. 10, 1996 PCT Filed Jan. 24, 1996 PCT Pub. No. WO96/24908 PCT Pub. Date Aug. 15, 1996In an optoelectronic recording element for point-by-point and line-by-line recording, the recording element is composed of a laser diode for generating a light beam, of an objective, of a light detector arranged spaced from the laser diode and of a reflector arranged turned in the beam path of the light beam that reflects a part of the light beam onto the light detector. The reflector is composed of concave mirror segments that are positioned between the laser diode and the objective. The reflector has an aperture whose center line coincides with the optical axis and whose diameter at least corresponds to the diameter of the light part of the light beam employed for the recording. As a result thereof, the light part of the light beam employed for the recording passes through the reflector loss-free, and the light part of the light beam that is not used is nearly completely focussed onto the light detector.
