The invention discloses a device for
polishing and fixing parts to a mold for a high-precision and low-deformation
germanium window and a method for fixing the parts to the mold, relates to the technical field of optical element
processing, and solves the technical problem that the method for
polishing and fixing the parts to the mold for the
germanium window cannot meet the requirements for
processing of the high-precision
germanium window in the prior art. According to the technical scheme, the device comprises an
adhesive mold, an
adhesive, a positioning ring and a positioning seat, whereinthe
adhesive is of a circular ring structure, and is bonded to an end face of the adhesive mold; a
flanging is arranged at the periphery of the positioning ring, and a central hole corresponding to the shape of the adhesive mold is arranged in the middle of the positioning ring; a stop collar is arranged on the surface of the positioning seat, the shape of the stop collar is corresponding to theshape of the
flanging of the positioning ring, and the stop collar is coaxial with the central hole; a to-be-polished germanium window is arranged in the stop collar, the positioning ring is buckled on the exterior of the stop collar, and one end, provided with the adhesive, of the adhesive mold passes through the central hole and the stop collar in sequence and is fixed to the germanium window through the adhesive.
