• 30 mm Cage Compatible Back Plate
• Magnetically Coupled Mounting Carriage
• Accepts Ø1" (25.4 mm) Optics up to 0.20" (5.1 mm) Thick
• Angular Repeatability Better than 1 µrad
• Lateral Repeatability Better than 10 µm in X, Y, and Z
• Back Plate and Mounting Carriage Have Internal SM1 Threading
• One Retaining Ring (SM1RR) Included

The CP90F consists of a back plate compatible with the 30 mm cage system and a mounting carriage (front plate) that is magnetically coupled with pairs of rare earth magnets to the back plate. For stability, precision, and repeatability, the mounting carriage contacts the back plate at three points. Each point of contact is a ball bearing on the mounting carriage resting in the groove formed by two parallel steel pins. Since the axes defined by the three sets of pins share a common point of intersection, the system is properly constrained (kinematic). The mounting carriage can be easily inserted or removed from the fully assembled cage system by separating it from the back plate, rotating it sideways, and then extracting it from the cage.

The internal SM1 threading allows components up to 0.20" (5.1 mm) thick to be secured in the mounting carriage with the included SM1RR retaining ring. Components with external SM1 threading, like the SM1A7 alignment guide, can be threaded onto the mounting carriage. However, components mounted in this way (OD = 1.2" (30 mm)) cannot extend more than 3/16" (4.7 mm) beyond the face of the mounting carriage without sacrificing the ability to remove the mounting carriage and component from a closed cage system. The lateral repeatability specification (10 µm) indicates that the X, Y, and Z position of the mount will not vary by more than
10 µm after being removed and replaced, while the 1 µrad angular repeatability refers to the rotation of the optic not changing by more than 1 µrad.

• Quick-Release Cage Mount with Adjustable SM1-Threaded (1.035"-40) Optic Cell
• Compatible with Ø1" and Ø25 mm Mounted and Unmounted Optics
• On- and Off-Axis Optic Alignment for use with Lenses, Filters, Mirrors, and Beamsplitters
• Quick-Release Flexure Clamping Mechanism for Secure Cage Mounting without Disassembly

The CP360R(/M) cage mount allows for 360° of manual rotation of an optic within a 30 mm cage system. Optics up to 7 mm thick can be mounted in the 0.45" (11.4 mm) long SM1-threaded (1.035"-40) optic cell using the two included retaining rings. The CP360R(/M) uses a flexure-style clamp with two 4-40 setscrews for quick connection without cage disassembly. The optic is turned perpendicular to the optical axis, and the mount "snaps" onto the cage rods. The CP360R(/M) can be mounted on any two of the four cage rods for either X- or Y-axis pivoting adjustment.

The optic can be rotated via the knurled knob or 3/16" (5 mm) hex, and the optic mount's pivot position can then be locked via a 4-40 setscrew. An engraved scale indicates the angle of the optic, with tick marks every 5°. Please note that when using with beamsplitters, the clear aperture will be an ellipse with a minor axis of approximately 0.315" (8 mm) when used at 45° AOI.

  SM1 Internal Thread Directly Compatible With Our SM1-Series Components
  Two Retaining Rings (SM1RR) Included

The QRC1A cage mount is equipped with a spring-loaded dovetail clamp that secures or releases the cage mount to two of the four ER rods in the cage structure. The cage plate has internal SM1 threading that allows for components up to 0.2" (5 mm) thick to be secured with the included SM1RR retaining ring. In addition, components up to 5/16" (7.9 mm) thick (not including length of threaded stub, OD = 1.2" (30 mm)) with external SM1 threading can be attached without sacrificing the ability to remove the cage plate from a closed cage system. For instance, all of the SM1 threaded ND filters can be used with this cage plate.

The STK01 cage plate allows Ø1" optics to be inserted or removed from a closed 30 mm cage structure. The cage plate uses two bands that are locked in place with the internal SM1 (1.035"-40) threading Ø1" optics up to 0.20" (5mm) thick to be secured in the cage plate using the included SM1RR retaining ring. In addition, components up to 5/16" (7.9 mm) thick (not including length of threaded stub, OD = 1.2" (30 mm)) with external SM1 threading can be attached without sacrificing the ability to remove the cage plate from a closed cage system.
