The OMH series of 45° optic adapters is designed to mount into our full range of mirror mounts including the IM100, and IXM100 series.  Their simple design enables the experimenter to build adjustable periscope assemblies for 0.5-inch (12-mm), 0.75-inch (19-mm), or 1.0-inch (25-mm) mirrors.  They use a single 8-32 (M4) nylon tipped set screw to securely hold the mirror in place without damaging it.  All models incorporate our one wrench design, in which the same wrench is used to lock the optic in place and adjust the angle of the adapter via the series of capstan holes around the circumference of the adapter.
