4-40 (M3) Mounting Stud for Post Mounting

Features

Rotation Mount with 360° Continuous Rotation
4-40 (M3) Stud for Post Mounting
SM05 (0.535"-40) Threaded Optic Bore for Ø1/2" Optics
Lockable Rotational Position
One SM05RR Retaining Ring Included

The MRM05(/M) is a lockable, continuous rotation mount for Ø1/2" optics. The mount features full 360° rotation of the mounting carriage, with a marking at every 2° engraved on the front face. The back of the mounting carriage has a knurled edge for easy grip. A setscrew with a 0.05" (1.3 mm) hex is located on top for locking the rotational position. The center aperture is SM05-threaded (0.535"-40) and accepts Ø1/2" (Ø12.7 mm) optics up to 5.8 mm thick. Optics are held in the mount with an included SM05RR retaining ring, which can be adjusted with an SPW603 or SPW801 spanner wrench. These mounts are designed to provide a 10 mm optic axis height when measured from the bottom of the mount to match our Mini-Series Kinematic Mounts.

The MRM05(/M) has a 4-40 (M3) mounting stud for post mounting (see image to the right), making this mount compatible with our Mini-Series Optical Post Assemblies. The mounting stud has a length that is optimal for mounting into posts, but can be removed if desired. The mounting hole has a depth of 0.09" (2.3 mm); caution should be taken in choosing a setscrew with the correct length, as damage to the part can occur.

Rotation Mount and Stage Selection Guide

Thorlabs offers a wide variety of manual and motorized rotation mounts and stages. Rotation mounts are designed with an inner bore to mount a Ø1/2", Ø1", or Ø2" optic, while rotation stages are designed with mounting taps to attach a variety of components or systems. Motorized options are powered by a DC Servo motor, 2 phase stepper motor, or an Elliptec™ resonant piezo motor. Each offers 360° of continuous rotation.
