Fixed SM-Threaded Optics Mounts
The LMR Series of fixed optics mounts are a convenient way to mount Ø1/2", Ø18 mm, Ø1", Ø30 mm, Ø1.5", Ø2", Ø75 mm, Ø100 mm, or Ø4" optics on TR Series posts via the #8-32 (M4) tapped hole on the base of the mount. Each LMR series part has an internally threaded hole equipped with a back edge lip on which the optic rests. The retaining ring included with each mount can then be used to secure the optic in place by sandwiching the optic between the back lip and the retaining ring. Additional retaining rings can be purchased separately, including stress free retaining rings for select diameters. The LMR series of fixed optics mounts are also used as a mount to hold optical components with external SM threading. The LMR05S (LMR05S/M), LMR1S (LMR1S/M), and LMR2S (LMR2S/M) have both internal and external SM1 threading. As shown in the picture on the right, the external SM1 threading allows a for a lens tube or some other SM-threaded component to be attached to the back side of the mount while still allowing an optic to be mounted using the internally threaded SM hole. Please note that the external threading option is only available for Ø1/2", Ø1", and Ø2" inch optics.
