The 50.8-mm (2-in.) Top-Adjust MHX-T series mirror mounts are all-stainless steel and feature adjustments that are conveniently accessible from the top of the mount. They are designed with a hollow frame that not only provides a higher moment of inertia to maximize stiffness but also thinner, reduced-mass sections, allowing it to reach thermal equilibrium faster than traditionally designed mounts. The hollow frame also serves to protect the front plate from being knocked from its kinematic points. Thermal repeatability tests validate the effectiveness of the new frame design, showing lower deflection and equivalent repeatability against rival mounts. The MHX mount is loaded with additional features like center-post mounting, adhesive wells, and vented keying pin slots, all in the most compact and affordable stainless steel mount. Knobs and locks are available but sold separately.

Details

In addition to the standard rear-mounted post holes, this mount also includes center-point mounting holes. These are positioned so that the rotation axis of the post passes directly through the mirror’s reflective plane. As a result, the optical beam stays centered on the mirror surface even when the mount is rotated. In contrast, using only rear-mounted post holes shifts the reflective surface off the optical axis during rotation. To address this, two forward-positioned center-point mounting holes are provided: the front hole is threaded M4, and the adjacent one is threaded 8-32. Use the M4 center-point hole when mounting the mirror in the forward orientation, and the 8-32 hole when mounting it in the rear-facing orientation. Each side of the mount includes two sets of these holes, giving a total of six mounting points. The rear-mounted post hole is unthreaded and accepts either M4 or 8-32 screws.

Weight	0.4600kgs
Guide	In addition, a special screw-on knob (MHX-K-M6) is also available and is ideal if frequent adjustments will be made. The knob has a hole throught the center to allow access to the hex key. A special lock (MHK-L-M6) for holding the adjusted angle is also available.
Attention	Each side of the mount includes a counterbored clearance hole, an M4-threaded hole, and an 8-32-threaded hole. In total, there are six mounting point options, which can be used individually or in combination to provide greater stability.
