Thorlabs KS1RS - Kinematic Rotation Mount for Ø1" Optics

• Three 1/4\"-80 Lockable Stainless Steel Adjusters with Removable Knobs and Brass Bushings for Smooth Adjustments
• Six #8 (M4) Counterbored Mounting Holes Allow Left-Handed or Right-Handed Orientations
• SM1-Threaded (1.035\"-40) Rotation Ring with Locking Screw

The KS1RS is designed to hold Ø1\" (25.4 mm) optics in situations where it is necessary to control the tip/tilt position as well as the rotation of the optic. It is also capable of translation along the z-axis, which is accomplished by turning all three tip/tilt adjusters equally in the same direction. This mount is ideal for polarization optics such as linear polarizers or wave plates. In addition, our Ø1\" round cylindrical lenses may also be mounted in the KS1RS when it is necessary to adjust the angle of the line produced at the focal plane. The KS1RS features an SM1-threaded bore capable of mounting Ø1\" optics up to 0.47\" (11.9 mm) thick using the included SM1RR retaining ring. Additionally, SM1 lens tubes may be threaded onto the mount to accommodate thicker optics.
