Quick-Release Cage Plates for the 30 mm Cage System
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
The CP360R snaps into pre-assembled cage systems, and can be used to mount optics both off-axis (such as a mirror mounted at 45°, shown on the right above) or on-axis.
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.
Dovetail Design Provides Smooth Release and Clamping Action
Accepts Ø1" (Ø25 mm) Optics up to 0.14" (3.6 mm) Thick
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.
Easy Placement and Removal of a Ø1" Optic Within an Assembled 30 mm Cage System
SM1 (1.035"-40) Tapped Hole Directly Accepts Optics Up to 0.20" (5.1 mm) Thick
Two Retaining Rings (SM1RR) Included
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. For instance, all of the SM1 threaded ND filters can be used with this cage plate.
