These Right-Angle Kinematic Cage Mounts provide kinematic tip and tilt adjustment for an optic at a mean angle of 45° relative to the optical axis. They are compatible with Thorlabs' cage systems and have internal SM threads at the input and output ports for mounting lens tubes (see the table below).

The KCB05(/M), KCB1(/M), and KCB2(/M) mounts have 4-40 tapped holes at the input and output spaced for compatibility with 16 mm, 30 mm, or 60 mm cage systems, respectively. As a result, SRSCA SR Rod Adapters [for Item # KCB05(/M)] or ERSCB ER Rod Adapters [for Item #s KCB1(/M) and KCB2(/M)] are necessary to connect, adjust, and lock two of these right-angle cage mounts together using cage rods.

The KCB05C(/M), KCB1C(/M), and KCB2C(/M) mounts have smooth bores that accept cage rods at the input and output. The KCB05C(/M) mount's bores are spaced for 16 mm cage system compatibility and have a 0.05" (1.3 mm) hex setscrews at each bore to lock an SR cage rod in place. The KCB1C(/M) and KCB2C(/M) mounts have bores spaced for 30 mm or 60 mm cage systems, respectively, and use 5/64" (2 mm) hex setscrews to lock ER cage rods in place. As a result, these mounts can be connected to another right-angle cage mount of the same size without the need for SCRCSA or ERSCB cage rod adapters.

The kinematic tip and tilt adjustment plate on each mount is actuated with fine adjustment screws for smooth, high-resolution movement. Optics are held with a nylon-tipped setscrew, and loaded from the backside. This arrangement does not limit the maximum thickness of the optic. The adjustment plate is double-bored for two lines of stable contact with the mating optic.

The ten right angle mounts listed below are sized to incorporate Ø1/2" (Ø12.7 mm), Ø1" (Ø25.4 mm), or Ø2" (Ø50.8 mm) optics within a 16 mm Cage System, 30 mm Cage System, or 60 mm Cage System, respectively.

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.

Total Length 25 mm (0.98") 41 mm (1.60") 71.1 mm (2.8")
Cage Components
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.
30 mm
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.

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.
30 mm
60 mm
Replacement Setscrews Replacement setscrews are offered for our 16 mm (SS4B013, SS4B025, and SS4B038) and 30 mm (SS4MS5 and SS4MS4) cage systems products.
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. Explore our Cage Systems Visual Navigation Guide to see the full range of Thorlabs' cage components.

Have you considered versions of these right angle kinematic cage mounts with lockable adjusters, similar to those on the KS05? These would be useful for more permanent installations. Also, a cover plate to go over the adjusters and the back of the mirror would be useful for the same. Thank you.

Thank you for contacting Thorlabs and for your feedback. We will consider both of these product improvements within our internal engineering forum.
hnguyen  (posted 2015-08-14 17:11:04.083)
You specify that the minimum thickness for optics that can be secured by KCB05 mount is 3 mm. Is there any way to hold a 1-mm thick optics in KCB05 mount? If so, please let me know your solution by e-mail as soon as possible. Thank you.
jlow  (posted 2015-08-25 04:20:07.0)
Response from Jeremy at Thorlabs: You will have to use a 2mm spacer so that the setscrew can engage your optic or permanently epoxy the optic in the mount.
samzlemieux  (posted 2013-04-23 19:10:38.887)
We are currently using the KCB1 in order to make a horizontal beam vertical. Right now, I can't find a way to put a post and a holder underneath the part, because the screw holes are located on the sides (with my configuration). If I use the side holes, I need a set of ankles, which make the set-up more unstable. Is there any way to add a plate or something?
tcohen  (posted 2013-04-24 21:33:00.0)
Response from Tim at Thorlabs: You could use two standard TR posts with an RA90 to access the (now side) mounting holes. The cage rods are on a 30mm square matrix, so you are able to flip the part 90 degrees and still use the cage system with ER rods as well (with a C1026 clamp if support is required). Alternatively, we have parts such as the MA45-2 (45 degree adapter) which may be preferred if you aren't using the cage axis/SM1 ports.

Please provide the additional information on this product : distance of the intersection position from the 45 degree surface, when the beams from the two SM1 tube entrances are entering to it at the tube central axes. We are looking for an attachment block for a fast steering mirror component that has a tilting mirror at the front surface. Possibly it could be connected using KCB1 if the kinematic mount of KCB1 is removed, provided that its 45 degree surface is in level, or not too far from the intersection point.

Photo is too hard to read, please give at least on tight shot, can't see how the optic is mounted.

The KCB2(/M) Right-Angle Kinematic Cage Mount provides kinematic tip and tilt adjustment of a Ø2" (Ø50.8 mm) optic held in a mounting plate with a mean horizontal position at a 45° angle. The ports are equipped with SM2-threaded (2.035"-40) bores. The KCB2(/M) has eight 4-40 tapped holes spaced to mate with our 60 mm cage systems. ERSCB ER Rod Adapters are necessary to effectively connect, adjust, and lock two of these right angle cage mounts together within the cage system. The ±4° kinematic tip and tilt adjustment plate is actuated with three 100 TPI (Threads per Inch) adjustment screws for smooth, high-resolution movement of 0.01" (0.254 mm) per rotation. 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 Ø2" (Ø50.8 mm) optics using a 5/64" (2 mm) hex key or balldriver via the mounts' rear-loading, double-bored hole. The rear loading design does not limit the maximum 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 0.24" (6 mm).

The KCB2C(/M) Right-Angle Kinematic Cage Mount provides kinematic tip and tilt adjustment of a Ø2" (Ø50.8 mm) optic held in a mounting plate with a mean horizontal position at a 45° angle. The ports are equipped with SM2-threaded (2.035"-40) bores and smooth bore holes spaced to mate with our 60 mm cage system standard. The cage rods are secured by setscrews using a 5/64" (2 mm) hex key or balldriver. This design allows multiple 60 mm cage components to be directly interfaced without the need for ERSCB ER Rod Adapters. The ±4° kinematic tip and tilt adjustment plate is actuated with three 100 TPI (Threads per Inch) adjustment screws for smooth, high-resolution movement of 0.01" (0.254 mm) per rotation. 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 Ø2" (Ø50.8 mm) optics using a 5/64" (2 mm) hex key or balldriver via the mounts' rear-loading, double-bored hole. When used with transmissive optics, two clearance cuts around this hole provide a Ø1.26" (Ø32.0 mm) nominal clear aperture for any transmitted light. The rear loading design does not limit the maximum 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 0.24" (6 mm).
