Right Angle Kinematic Cage Mounts are designed to allow the functions of a kinematic optic mount to be easily integrated with Thorlabs' cage systems and SM lens tubes.

These mounts provide kinematic tip and tilt of an optic held in an adjustment plate with a mean horizontal position at a 45° angle. The KCB05(/M), KCB1(/M), and KCB2(/M) have ports equipped with SM-threaded bores and four 4-40 tapped holes spaced to mate with our SR cage rods for 16 mm cage systems or ER cage rods for 30 mm and 60 mm cage systems. SRSCA SR Rod Adapters [for KCB05(/M) mounts] or ERSCA ER Rod Adapters [for KCB1(/M) and KCB2(/M) mounts] are necessary to connect, adjust, and lock two of these right angle cage mounts together using cage system standards.

The KCB1C(/M) and KCB2C(/M) have ports with eight smooth cage rod bores spaced to mate with our cage system rods. Cage rods are secured in these holes by setscrews using a 5/64" (2 mm) hex key or balldriver. This allows the KCB1C(/M) and KCB2C(/M) to connect with another right angle cage mount without the need for the ERSCA ER rod adapter. The entrance and exit ports on the KCB1C(/M) and KCB2C(/M) are SM-threaded to interface with Thorlabs' lens tubes.

The kinematic tip and tilt adjustment plate on these mounts 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; each mount is also compatible with SM05, SM1, or SM2 lens tube systems.

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. Among the most essential of these fundamental components are cage plates and cage assembly rods.

Mechanical Support Drawing Of CP02 Cage Plate

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 to right). The 16 mm SP series is designed for use with Ø1/4" and Ø1/2" optics. The 30 mm cage standard, using CP series cage plates, is ideally suited for compact assemblies based around Ø1/2" and Ø1” optics. Lastly, the 60 mm cage standard, using LCP series cage plates, is designed for Ø1” and Ø2” optics.

Standard Mating Parts

The flexibility inherent to the Cage Assembly System lies within its reliance on well-defined mounting and thread standards designed for direct interfacing 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 industries most common optic sizes.  Essential building blocks, such as our popular lens tubes, directly interface to these standards.

A broad range of optomechanical positioning mounts and rigid construction components are designed for interfacing with the 16 mm, 30 mm, and 60 mm cage assembly rod spacing. (See Visual Navigation Product Overview).

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.

jouko.viitanen  (posted 2008-10-27 06:48:27.0)
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.
