SUPPORT FOR A TRANSMISSION OPTICAL ELEMENT, LASER PROCESSING DEVICE COMPRISING SUPPORT OF THIS TYPE, AND METHOD FOR ADJUSTING THE POSITION OF A TRANSMISSION

The invention relates to a holder (100) for a transmissive optical element (105), the holder (100) having a frame (110) and a mounting (120) for the transmissive optical element (105). The mounting (120) is mounted in the frame (110) by means of two adjusting elements (130) and a guide pin (140) arranged between the adjusting elements (130), and the distance of the mounting relative to the frame (110) can be adjusted. The adjusting elements (130) are each mounted in the frame (110) such that the adjusting elements can be pivoted and can be adjusted independently of one another with respect to their respective lengths. The mount-side ends (132) of the adjustment elements (130) may each be pivoted in the mount (120) and attached such that the adjustment elements may be displaced in a longitudinal direction of the respective adjustment element (130). A frame-side end portion (144) of the guide pin (140) is fixed to the frame (110), and the frame-side end portion (144) of the guide pin (140) is pivotally mounted
