Cage Rod Mounting Options

• Four Internally SM2-Threaded (2.035"-40) Ports
• 4-40 Tapped Holes on Four Faces for Securing Ø6 mm Cage Rods
• Ø6 mm Through Holes for Ø6 mm Cage Rods

The LC6WR 60 mm Cage Cube is designed for building 2D and 3D cage systems while providing a means to mount optics such as beamsplitters inside. Two opposing faces offer Ø6 mm through holes, while the other four faces have 4-40 tapped holes to accept cage rods. The through holes allow for 1D translation of a section in a cage assembly. There are four 8-32 tapped holes (see photo to the right) on the top and bottom of the cube for connecting various accessories, such as cover plates or platforms, which can be found below. The 8-32 cap screws needed for mounting these accessories are included with the individual accessory and not the LC6WR Cage Cube. The four internally SM2-threaded ports allow the cubes to be integrated with other accessories, such as our Ø2" Lens Tubes; unused ports can be closed off with an SM2CP2 Port Hole Cover.

Eight M4 setscrews with a 5/64" (2.0 mm) hex are included to secure the cube to the cage rods that pass through the through holes of the cage cube.

LB1C Light-Tight Blank Plate

• LB1C(/M): Blank Cube Cover Plate; 1/4"-20 (M6 x 1.0) Tapped Hole for Post Mounting
• LB2C: SM2-Threaded Cube Cover Plate for Attaching SM2 Lens Tubes and Accessories
• Compatible with LC6WR Cage Cube
• 4-40 Tapped Holes for 60 mm Cage Systems

Two cover plates are offered for the LC6WR 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 is an internally SM2-threaded cage cube plate, which allows SM2-threaded components to mate to the top or bottom faces of the LC6WR cube.

Four 8-32 cap screws are included for attachment to the LC6WR Cage Cube sold above.

• Mounting Platform Fits into the Top or Bottom of LC6WR Cage Cube
• LB3C(/M) Features Sixteen 6-32 (M4) Tapped Holes
• LB4C(/M) Offers ±3° Pitch, ±3° Yaw, and 0.25" (6.35 mm) Z Translation and Eight 6-32 (M4) Tapped Holes
• Ideal for Mounting Beamsplitter Cubes, Prisms, or 2" Optics (Mounts Sold Separately Below)
• Bottom-Located 8-32 (M4) Tapped Hole for Mounting to Ø1/2" Posts

The LB3C(/M) and LB4C(/M) platforms mount into the top or bottom of our LC6WR cage cubes. Four cutouts in the platforms enable them to be secured to the LC6WR via the four included 8-32 locking screws. The 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 the optic mounts sold separately below. These tapped holes may also be used with a PM3(/M) or PM4(/M) clamping arm to hold prisms.

The LB3C platform is rigid and allows coarse manual rotational positioning, while the LB4C platform has three adjusters to provide pitch, yaw, and 0.25" (6.35 mm) Z translation in addition to manual rotational positioning. The LB4C's kinematic adjustment comes from three 1/4"-80 adjusters which have a 5/64" (2 mm) hex. The bottom of each platform has an 8-32 (M4) tapped hole, allowing it to be mounted onto a Ø1/2" Post.

• Clamp Objects Within LC6WR Cage Cube
• 5/32" (4 mm) Hex Socket on Screw Clamp
• Delrin®* Swivel Head Clamp

The LB6C cage cube clamp is compatible with the LC6WR 60 mm cage cube. The clamping mechanism comes from a 5/16"-18 screw 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 to the right.

Four 8-32 cap screws are included for attachment to the LC6WR Cage Cube sold above.

LFFM1 Rectangular Filter Holder shown mounted to a LB3C Cube Platform in a LC6WR Cube.

• Holds Rectangular or Square Filters Up to 4.0 mm Thick
• Accommodates Filters up to 2.5" (63.5 mm) Tall and 30 - 53 mm Long Inside a LC6WR Cage Cube
• Two Spring-Loaded Clamping Mechanisms Secure Optic's Position
• Compatible with LB3C(/M) and LB4C(/M) Platforms

The LFFM1 Cage-Compatible Filter Holder is specifically designed to hold rectangular or square filters up to 2.5" (63.5 mm) tall and 30 mm - 53 mm Long inside a LC6WR cage cube (see photo to the right). When used with the LB3C or LB4C mounting platforms, this mount enables dichroic filters, colored filters, beamsplitters, or ND filters to be placed at any angle with respect to the incident light.

Rectangular filters up to 4.0 mm thick can be held using two spring-loaded clamping arms designed to avoid scratching of a filter's interference coating; simply apply a horizontal force to the spring-loaded clamps, seat the optic into the channel created, and release the clamps, which leaves the optic wedged between a stop and a clamp at each end.

The LFFM1 can be directly mounted to Ø1/2" posts via the #8 counterbore which accepts 8-32 (M4) cap screws. Two 6-32 cap screws and two M4 cap screws are included for securing the holder to the LB3C(/M) or LB4C(/M) mounting platforms. The outside and inside engraved witness lines help line up the LFFM1 with the mounting positions for the LB3C(/M) and LB4C(/M) platforms. The optic and filter mount should be installed onto a mounting platform before being inserted into the cage cube.

• LB5CT1 Holds Ø2" (50.8 mm) Optics up to 0.26" (6.6 mm) Thick
• LB5CT2 Holds Ø2" (50.8 mm) Optics up to 0.48" (12.3 mm) Thick
• SM2-Threaded with Included SM2RR Retaining Ring
• Compatible with LB3C(/M) and LB4C(/M) Platforms

The LB5CT1 and LB5CT2 SM2-threaded Optic Mounts hold Ø2" optics on our 60 mm Cage Cube Rotatable Platforms. The LB5CT1 and LB5CT2 Mounts hold optics up to 0.26" (6.6 mm) or 0.48" (12.3 mm) thick, respectively, using an SM2RR retaining ring (included). The deeper design of the LB5CT2 mount reduces the clear aperture when used with transmissive optics such as beamsplitters, making it ideal for mounting mirrors. Each mount is attached to imperial cage cube platforms using a 6-32 button head screw (7/64" hex) and washer and to metric cage cube platforms using an M4 screw (3 mm hex) and washer (all mounting hardware included).

When used in an LC6WR cage cube, the mount can center the optic within the cube. This is particularly important when mounting a mirror in the cube. Witness lines are engraved on the sides of the mount for aid in alignment. These witness lines mark the position of the optic's front surface when inserted into the mount with the front face directed towards the screw's mounting slot.
