Right-Angle Kinematic Mounts for Elliptical Mirrors allow elliptical optics to be mounted at a 45° angle within a cage system or lens tube system. Elliptical optics have the advantage of a circular aperture when mounted at 45°. The KCB05E(/M) and KCB1E(/M) feature tapped holes for cage rods on both the entrance and exit ports, while KCB1EC(/M) and KCB2EC(/M) feature smooth bores for cage rods. All of these mounts have SM-threaded entrance and exit holes for lens tube integration.
The eight right-angle mounts listed below are sized to incorporate 1/2", 1", or 2" elliptical optics within a 16 mm, 30 mm, or 60 mm cage system, respectively. These mounts are compatible with our dielectric and metallic elliptical mirrors. We also offer Fixed 45° Mounts for our 1" and 2" elliptical mirrors.
The RBP1(/M) Pin-Aligned, Clamping Post Base, available below, is designed to align the surface of a mirror mounted in a KCB1E(/M) or KCB1EC(/M) Right-Angle Kinematic Mirror Mount above a hole in the optical table, simplifying the process of aligning a reflected laser beam over the table's threaded holes. To use this clamping base, the KCB1 series mount must be attached to a Ø1" or Ø25 mm Pillar Post.

(posted 2017-12-21 12:21:59.633) I am not able to open the step file for the KCB2EC/M with 2 different software (IDA-step and Inventor). Is the file corrupted? Can you fix it?
Thank you for your promt answer in advance

(posted 2018-01-04 01:42:05.0) Thank you for contacting Thorlabs. There are several types of step files that may be compatible with ida-step & Inventor. I will reach out to you directly to provide these step files to try for IDA-step and Inventor and help troubleshoot this issue. syim
(posted 2013-09-24 11:55:01.567) Can you provide the elliptical mirror mount part separately? I don't need the cage. Thanks. cdaly
(posted 2013-09-26 13:27:00.0) Response from Chris at Thorlabs: Thank you for using our feedback tool. We do sell fixed elliptical mirror mounts, which do not involve the cage ssytems. The 2" elliptical mirror mount is the H45E2, which can be post mounted, turned vertically with a fixed optic mount like FMP2, or mounted kinematically using the KM200. walter.mueller
(posted 2013-05-22 17:30:44.36) Gibt es von diesem Halter KCB1E tatsächlich nur die universelle zöllische Version? Es müsste doch eine mit Metrischem Gewinde für den Post geben? jlow
(posted 2013-05-22 16:07:00.0) Response from Jeremy at Thorlabs: There's no special metric version of the KCB1E. It has both #8-32 and M4x0.7mm mounting holes. tcohen
(posted 2013-01-22 09:23:00.0) Response from Tim at Thorlabs: Thank you for your feedback! Right now we are releasing many new products, but expanding our elliptical selection for both dichroics and beamsplitter plates are being discussed. We are grateful for your feedback to help aid us in continuing to offer new products that would be the most useful for our customers. cafortin

- Eight 4-40 Tapped Holes to Mate with 16 mm Cage Systems
- Mounts 1/2" (12.7 mm) Elliptical Optics at a 45° Angle to the Optical Axis
- 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)
- KCB05E/M: One M3 Tap and One M4 Tap (for Mini-Series, Ø1/2", and Ø25.0 mm Posts)
The KCB05E(/M) Elliptical Mirror Mount provides ±4° of kinematic pitch and yaw adjustment for a 1/2" elliptical optic positioned at a mean angle of 45° to the optical axis. 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).

The ports are equipped with SM1-threaded (1.035"-40) bores and four 0.25" (6.35 mm) deep smooth bore holes spaced to mate with our 30 mm cage system standard.

The KCB2EC(/M) Right-Angle Kinematic Cage Mount provides kinematic pitch and yaw adjustment of a 2" (50.8 mm) elliptical optic held in a mounting plate with a nominal horizontal position at a 45° angle. The ports are equipped with SM2-threaded (2.035"-40) bores and four 0.195" (5.0 mm) deep smooth bore holes spaced to mate with our 60 mm cage system standard.
The ±3° kinematic pitch and yaw adjustment plate is actuated with three 100 TPI (threads per inch) adjustment screws that provide angular resolution of 4.5 mrad/rev. The pitch and yaw adjusters include removable knobs with Ø5/64" (Ø2 mm) side holes for fine adjustments, while the third adjuster 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 setscrew mounted on a swing arm is used to secure 2" (50.8 mm) elliptical optics using a 5/64" (2 mm) hex key or balldriver via the mount's rear-loading, double-bored hole. Note that the setscrew should only be finger tight to avoid distorting the optic. Please note that this mount is compatible only with 2" elliptical optics that are 0.47" (12 mm) thick. Our selection of dielectric and metallic elliptical mirrors are compatible with this mount.

Click to Enlarge Using a BHM6 Ruler and RBP1 Base to Align a KCB1 Mount
The RBP1(/M) Pin-Aligned, Clamping Post Base is designed to simplify aligning a laser beam over the threaded holes in an imperial or metric optical table by holding the front surface of a mirror mounted in a KCB1(/M), KCB1C(/M), KCB1E(/M), or KCB1EC(/M) Right-Angle Kinematic Mirror Mount above a hole in the table. The clamping post base accepts Ø1" (Ø25 mm) Pillar Posts, to which the right-angle mirror mount can be connected as shown in the image to the left; note that the base does not accept pedestal posts. Alignment pins on the bottom of the RBP1(/M) clamp fit into the holes on an optical table, which sets the mount in the correct position, while a 1/4"-20 (M6) cap screw and washer (not included) secure the clamp to the table. The body of the clamp is made of stainless steel, with an additional anodized aluminum piece that works with the locking screw to lock the post to the clamp.
Once the RBP1(/M) is attached to the table, the angle of the post can be set so that the mirror sends the beam along the general direction of the holes in the table by aligning the center of the back of the mount over the locking screw side of the clamp, as shown in the image above and to the right. To secure the post in place, tighten the locking screw with a 3/16” (5 mm) hex key or balldriver. The post clamping mechanism uses three points of contact for stable mounting (see the image to the upper right). The knobs on the mirror mount can then be used for further precise alignment of the beam. We recommend the BHM6 Magnetic Beam Height Ruler with Dowel Pins as an ideal tool for aligning a laser with a table's hole pattern using the RBP1(/M) post bases, as it places a series of alignment holes at different heights above two threaded holes in the table (see the image to the left).
