90° Flip Mounts are ideal for easily flipping mounted optics in and out of a beam path. An angular repeatability of <100µrad helps to ensure mounted optics maintain alignment relative to the optical path after repeated adjustments of the mount. These flip mounts feature both female threaded and counterbored mounting holes for added versatility. 90° Flip Mounts are designed with a 25.4mm (1”) thickness to maintain simple and consistent operating heights between optical elements when mounted to an optical post. The mounting holes are available in both Metric (M4 tap and M4 counterbore with internal M6 threading), or English (8/32 tap and 8/32 counterbore with internal ¼-20 threading) options for adaptability in any benchtop optical system.
