The KC05-T 16 mm Cage System Compatible, Kinematic Mirror Mount is designed for Ø1/2" (Ø12.7 mm) mirrors. This three adjuster mount provides ±2.5° of tip/tilt adjustment. By adjusting all three adjusters at once, the mirror can also be translated along the cage's axis. The SM05-threaded (0.535"-40) mounting hole accepts thin mirrors up to 0.15" (3.8 mm) thick.

The KCB05(/M) and KCB05C(/M) Right-Angle Mounts accept Ø1/2" (Ø12.7 mm) round mirrors, and the KCB05E(/M) Right-Angle Mount accepts 1/2" elliptical mirrors. Both the entrance and exit ports have 4-40 threaded holes or Ø4 mm bores for SR cage rods to support 16 mm cage system integration, as well as SM05 internal threads for compatibility with Ø1/2" lens tubes. Each mount has three M3 x 0.25 adjusters for precise tip and tilt adjustment of the optic, useful for compensating beam path deviation in a 16 mm cage system.

Cage System Compatibility: Thorlabs offers 16 mm, 30 mm, and 60 mm cage systems designed for Ø1/2", Ø1", and Ø2" optical components, respectively. The parts on this page are compatible with our 16 mm cage system and utilize Ø4 mm SR cage rods.

Cage System Overview

The 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 Standards

Thorlabs 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 accommodate 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 Threads

The 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.

Dear tech support, what is the distance between the center of the reflecting surface and the front surface of the KCB05C/M mount ? It is not clear to me in the CAD pdf file. Same question for its 1" optics version. Thank your for your help.

Thank you for contacting Thorlabs. I reached out to you directly to clarify that the measurement you are seeking is the distance from the back of the mounted mirror to the face of one of the other two sides of the mount, in the center of the SM- threaded aperture. For KCB05C, this distance would be 17.32 mm. For KCB1C, it would be 23.87 mm.

The KCB05(/M) Mirror Mount provides provides ±4° of kinematic tip and tilt adjustment for a Ø1/2" optic positioned at a mean angle of 45° to the optical axis. Entrance and exit ports are equipped with an SM05-threaded (0.535"-40) hole. The KCB05(/M) has eight 4-40 tapped holes spaced for compatibility with our 16 mm cage systems. SRSCA SR Rod Adapters are necessary to effectively connect, adjust, and lock two of these right angle cage mounts together within the cage system. The kinematic tip and tilt adjustment plate on these cubes is actuated with M3 x 0.25 adjustment screws that allow for smooth, high-resolution movement of 0.25 mm (0.01") per turn. Two of these adjusters include removable knobs, while the third must be tuned with a 5/64" (2 mm) hex key or balldriver.

A nylon-tipped setscrew is used to secure Ø1/2" (12.7 mm) optics using a 0.05" (1.3 mm) hex key or balldriver in the mount's rear-loading, double-bored hole. The rear loading design does not limit the thickness of the mounted optic and the mounted optic remains accessible even after the mount is fitted with cage rods or lens tubes. The minimum thickness for optics that can be secured by these mounts is 0.12" (3 mm).

The KCB05C(/M) Mirror Mount provides ±4° of kinematic tip and tilt adjustment for a Ø1/2" optic positioned at a mean angle of 45° to the optical axis. Entrance and exit ports are equipped with an SM05-threaded (0.535"-40) hole. Eight 0.20" (5.0 mm) deep bores, spaced for compatibility with our 16 mm Cage System, accept SR Cage Rods, which can be locked in place using the included 0.05" (1.3 mm) hex setscrews. This design allows multiple 16 mm cage components to be directly interfaced without the need for SRSCA SR Rod Adapters. The kinematic tip and tilt adjustment plate on these cubes is actuated with M3 x 0.25 adjustment screws that allow for smooth, high-resolution movement of 0.25 mm (0.01") per turn. Two of these adjusters include removable knobs, while the third must be tuned with a 1.5 mm hex key or balldriver.

A 0.05" (1.3 mm) hex, nylon-tipped setscrew is used to secure Ø1/2" (12.7 mm) optics in the mount's rear-loading, double-bored hole. Two clearance cuts, positioned on opposite sides of the optic bore, maximize the clear aperture for transmitted light and provide easy access to mounted optics. Due to the rear-loading design, the mounted optic remains accessible even after the mount is fitted with cage rods or lens tubes. The mount accepts optics ≥0.12" (3 mm) thick.
