60 mm Cage Cubes
3" Square Cube for 60 mm Cage Systems
Click to Enlarge
The LC6W is a 60 mm cage cube designed for building 2D cage systems while providing a means to mount optics such as beamsplitters inside. Two opposing faces have tapped holes to accept ER cage rods, while the other two opposing faces offer through holes. This allows for 1D translation of a section in a cage assembly. The eight included 4-40 setscrews are used to secure the cube to the cage rods that pass through the through holes of the cage cube.
Two cube plates are offered for the LC6W cube. The LB1C(/M) is a blank cover plate that is designed to provide a light-tight environment within the cube via a rubber o-ring. The opposite side of this plate features one centered 1/4"-20 (M6) tapped hole for mounting purposes. The LB2C (/M) is an SM2-threaded cage cube plate, which allows SM2-threaded components to mate to the top or bottom faces of the LC6W cube.
The LB3C and LB4C prism platforms mount into the top or bottom of our LC6W cage cubes. They can be mounted at almost any angle within the cage cube using the four 8-32 locking screws. Each LB3C platform features sixteen 6-32 (M4) tapped holes, while the LB4C has eight 6-32 (M4) tapped holes, which can be used to mount our LB5C optic mount (featured below). These tapped holes may be used with our PM3 (/M) clamping arm to hold items such as prisms.
The LB3C (/M) platform is rigid and only offers rotational positioning, while the LB4C (/M) platform has three adjusters to provide pitch, yaw, and 0.25" Z-translation in addition to rotational positioning. The LB4C's kinematic adjustment comes from three 1/4"-80 adjuster screws. The bottom each platform has an 8-32 (M4) tapped hole, thereby allowing it to be mounted onto a TR series post.
The LB6C cage cube clamp is compatible with the LC6W 60 mm cage cube. The clamping mechanism comes from a 5/16"-18 adjuster with a Delrin swivel tip to help avoid marring the clamped object. This adjuster features a 5/32" (4 mm) hex socket to loosen or tighten the clamp. The cube clamp plate features an O-ring, which can be used to form a light tight cage cube when used with the LB1C blank plates and C4W cube. Please note that a blank cover plate (LB1C) or cage cube platform (LB3C, LB4C) must be used in conjunction with the clamp. This clamp is best suited for use with rectangular objects and other objects with parallel top and bottom surfaces. The maximum and minimum object thicknesses are listed in the table below.
The LB5C optic mount holds a Ø2" optic on a rotatable platform (above). The mount holds an optic via three nylon screws and, when used within an LC6W cage cube, centered in the cube.
