摘要： The present application relates to a holder (100) for a transmissive optical element (105), the holder (100) having a frame (110) and a mount (120) for the transmissive optical element (105). The mount (120) is mounted within the frame (110) with two adjusting elements (130) and with a guide pin (140) arranged between the adjusting elements (130) and its distance from the frame (110) can be adjusted. The adjusting elements (130) are each mounted in the frame (110) so that they can pivot and are adjustable in their respective lengths independently of one another. The mount-side ends (132) of the adjusting elements (130) can each be pivoted in the mount (120) and are attached so that they can be displaced in the longitudinal direction of the respective adjusting element (130). The frame¬ side end (144) of the guide pin (140) is fixed to the frame (110), and the frame-side end (144) of the guide pin (140) is pivotably mounted in the frame (110) in the X and Y directions and slidable in the longitudinal direction of the guide pin (140).
