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.

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 Andreas

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.

Can you provide the elliptical mirror mount part separately? I don't need the cage. Thanks.

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.

Gibt es von diesem Halter KCB1E tatsächlich nur die universelle zöllische Version? Es müsste doch eine mit Metrischem Gewinde für den Post geben?

Response from Jeremy at Thorlabs: There's no special metric version of the KCB1E. It has both #8-32 and M4x0.7mm mounting holes.

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.

It would be nice to have a selection of elleptical dichroic filters to fit those kinematic mount.

KCB05E Elliptical Mount with SR Cage Rods and an SM05 Lens Tube
  • 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:

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).

The KCB1E(/M) right-angle mount provides pitch and yaw adjustment for a 1" (25.4 mm) elliptical optic held in a mounting plate whose nominal horizontal position is at a 45° angle. The ports are equipped with SM1-threaded (1.035"-40) bores and four 4-40 tapped holes center-to-center spaced to mate with our 30 mm Cage System standard. The kinematic pitch and yaw adjustment plate is actuated with 100 TPI (Threads per Inch) adjustment screws that provide angular resolution of 7.6 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" (25.4 mm) elliptical optics using a 0.05" (1.3 mm) hex key or balldriver via the mount's rear-loading, double-bored hole.

The KCB1EC(/M) right-angle mount provides pitch and yaw adjustment for a 1" (25.4 mm) elliptical optic held in a mounting plate whose nominal horizontal position is at a 45° angle. 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 cage rods are secured by eight setscrews using a 5/64" (2 mm) hex key or balldriver. This design allows multiple 30 mm cage components to be directly interfaced without the need for ERSCA ER Rod Adapters. The kinematic pitch and yaw adjustment plate is actuated with 100 TPI (Threads Per Inch) adjustment screws that provide angular resolution of 7.6 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-coated spring clip is used to secure 1" (25.4 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 ensures that the optic remains accessible even after the mount is fitted with cage rods or lens tubes. These mounts were designed to hold a 6 mm thick elliptical optic. We offer dielectric and metallic elliptical mirrors, which are compatible with these mounts.

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.
