Features
- Ø1/2" (Ø12.7 mm) Optic Mount
- Compatible with 16 mm Cage System
- Three Adjuster and Right Angle Mounts
- Post Mountable
The KC05-T is a 16 mm cage system compatible mirror mount, designed for Ø1/2" (Ø12.7 mm) mirrors. It is a three adjuster mount, offering ±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 KC05-T features a threaded mounting hole instead of a bore and is designed to hold thin mirrors up to 0.15" (3.8 mm) thick.
The KCB05(/M) and KCB05E(/M) are right angle mirror mounts for Ø1/2" (Ø12.7 mm) mirrors and 1/2" (12.7 mm) elliptical mirrors, respectively. They feature tapped holes for Ø4 mm cage rods on both entrance and exit ports for 16 mm cage system integration, as well as SM05-threaded entrance and exit holes for Ø1/2" lens tube integration. These mounts have three M3 x 0.25 adjusters, which allow for precise alignment of a mirror and make these mounts great 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 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 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.

|---|---|---|
| Cage Rods | 16 mm | These rods are used to connect cage plates, optic mounts, and other components in the cage system. The SR Series Cage Rods are compatible with our 16 mm cage systems, while the 30 mm and 60 mm cage systems use ER Series Cage Rods. |

| 60 mm | ||
| Cage Plates | 16 mm | These serve as the basic building blocks for a cage system. They may have SM-threaded central bores, smooth bores sized for industry standard optics or to accommodate the outer profile of our SM Series Lens Tubes, or specialized bores for other components such as our FiberPorts. |

| Optic Mounts | 16 mm | Thorlabs offers fixed, kinematic, rotation, and translation mounts specifically designed for our Cage Systems. |

| 60 mm | ||
| Cage Cubes | 16 mm | These cubes are useful for housing larger optical components, such as prisms or mirrors, or optics that need to sit at an angle to the beam path, such as beamsplitters. Our cage cubes are available empty or with pre-mounted optics. |

| Post and Breadboard Mounts and Adapters | Mounting options for cage systems can be found on our Cage System Construction pages. Cage Systems can be mounted either parallel or perpendicular to the table surface. | |
| Size Adapters | Cage System Size Adapters can be used to integrate components from different cage system and threading standards. | |
| Specialized Components | Thorlabs also produces specialized cage components, such as Filter Wheels, a HeNe Laser Mount, and a FiberPort Cage Plate Adapter, allowing a wide range of our products to be integrated into cage-mounted optical systems.

- Mounts Ø1/2" (Ø12.7 mm) Optics
- Provides ±2.5° Kinematic Tip and Tilt Adjustment
- SM05 (0.535"-40) Threaded Mounting Bore for Thin Optics
- 16 mm Cage Compatible
- Post Mountable: Two #8-32 (M4) Tapped Holes
The KC05-T Kinematic Mount is designed for our 16 mm cage systems. Four SR series cage rods can be passed through the mount and locked into place using setscrews. Each kinematic mount features three 3/16"-100 fine adjustment screws, offering an adjustment per revolution of 9 mrad/rev. The adjusters have a 5/64" hex socket for adjustment, and one 5/64" hex key is included with each mount. The KC05-T(/M) is SM05-threaded, which allows it to hold thin optics and can hold optics up to 0.15" (3.8 mm) thick. The KC05-T Kinematic Mount includes two SM05RR Retaining Rings to secure optics within the mount.

- Mounts Ø1/2" (12.7 mm) Optics at a 45° Angle to the Optical Axis
- Provides ±4º Kinematic Tip and Tilt Adjustment
- Compatible with SM05-Threaded (0.535"-40) Lens Tubes
- Post Mountable:
- KCB05: One 4-40 Tap and One 8-32 Tap (for Mini-Series and Ø1/2" Posts)
- KCB05/M: One M3 Tap and One M4 Tap (for Mini-Series, Ø1/2", and Ø1" Posts)
The KCB05(/M) cube provides kinematic tip and tilt of an optic held in a mounting plate whose mean horizontal position is at a 45° angle. 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 via the mounts' 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).

- Mounts 1/2" (12.7 mm) Elliptical Optics at a 45° Angle to the Optical Axis
- Eight 4-40 Tapped Holes to Mate with 16 mm Cage Systems
- Provides ±3º Kinematic Pitch and Yaw Adjustment
- Z-Axis Translation Using All Three Adjusters: ±0.04" (±1.0 mm)
- Compatible with SM05-Threaded (0.535"-40) Lens Tubes
- Post Mountable:
- KCB05E: One 4-40 Tap and One 8-32 Tap (for Mini-Series and Ø1/2" Posts)

The KCB05E(/M) cube provides kinematic pitch and yaw of a 1/2" (12.7 mm) elliptical optic held in a mounting plate whose nominal horizontal position is at a 45° angle. The ports are equipped with SM05-threaded (0.535"-40) bores and four 4-40 tapped holes center-to-center spaced for compatibility with our 16 mm cage systems. The kinematic pitch and yaw adjustment plate is actuated with M3 x 0.25 threaded adjustment screws that provide angular resolution of 12.94 mrad/rev. Two of these adjusters include removable knobs, while the third must be tuned with a 5/64" (2 mm) hex key or balldriver. While the optic face is nominally centered within the mount, the third adjuster can be used for fine tuning the position along the optical axis.
A nylon-tipped adjustment screw and a nylon-coated spring clip are used to secure 1/2" (12.7 mm) elliptical optics using a 0.05" (1.3 mm) hex key or balldriver via 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. We offer dielectric and metallic elliptical mirrors, which are compatible with this mount. The minimum thickness for optics that can be secured by these mounts is 0.12" (3 mm).
