Pivoting Quick-Release Ø1" Optic Mount for 30 mm Cage System![]()
Application Idea The CP360R Snaps into Place without Back Pivot Adjustment Pivot Adjustment CP360R 30 mm Quck-Release Pivoting Mount Front ![]() Please Wait The CP360R is easily snapped into and removed from preassembled cage sections, as shown in the animation above. It can be used to mount optics at variable angles of incidence (AOI), as shown below. Features
The CP360R 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 uses a flexure-style clamp with two 4-40 (0.050" hex) setscrews to quickly connect the mount without disassembling the cage. Simply turn the optic perpendicular to the cage system's optical axis and loosen the setscrews enough to allow the flexure mechanism to snap onto the cage rods. The CP360R can be mounted on any two of the four cage rods for either X- or Y-axis pivoting adjustment. By slightly loosening the locking setscrews, the cage mount can also be slid along the cage rods. 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. Thorlabs also offers a larger version of this item for 60 mm cage systems designed to mount Ø2" optics, which can be found here. ![]() Click to Enlarge The CP360R can be mounted on cage rods inside a C6W cage cube to hold a Ø1" optic at any chosen angle. ![]() Click to Enlarge Ø1" Mirror at 45° AOI ![]() Click to Enlarge Ø1" Filter at 0° AOI Cage System OverviewThe Cage Assembly System provides a convenient way to construct large optomechanical systems with an established line of precision-machined building blocks designed for high flexibility and accurate alignment. 16 mm, 30 mm, and 60 mm Cage System StandardsThorlabs offers three standards defined by the center-to-center spacing of the cage assembly rods (see image below). The 16 mm cage, 30 mm cage, and 60 mm cage standards are designed to accomodate Ø1/2", Ø1", and Ø2" optics, respectively. Specialized cage plates that allow smaller optics to be directly inserted into our larger cage systems are also available. Standard ThreadsThe flexibility of our Cage Assembly System stems from well-defined mounting and thread standards designed to directly interface with a wide range of specialized products. The three most prevalent thread standards are our SM05 Series (0.535"-40 thread), SM1 Series (1.035"-40 thread), and SM2 Series (2.035"-40 thread), all of which were defined to house the industry's most common optic sizes. Essential building blocks, such as our popular lens tubes, directly interface to these standards. ![]() An example of the standard cage plate measurements determining cage system compatibility.
