• Mounts Ø2" (Ø50.8 mm) Optics Along the Optical Axis of a 60 mm Cage System
• Through Holes for ER Cage Rods
• Provides ±3° Kinematic Tip and Tilt Adjustment
• KC2L(/M): Secures Optics with a Nylon-Tipped Setscrew
• KC2T(/M): SM2-Threads for Mounting Optics, Includes Two SM2RR Retaining Rings
• Post Mountable: Three 8-32 (M4) Tapped Holes

Our KC2L(/M) and KC2T(/M) Mounts provide kinematic tip and tilt adjustment of a Ø2" (Ø50.8 mm) optic. The KC2L(/M) includes a nylon-tipped setscrew to secure optics using a 5/64" (2 mm) hex key or balldriver. In contrast, the KC2-T(/M) is SM2-threaded and includes two SM2RR retaining rings to secure optics. Each mount has four through holes compatible with our ER Cage Rods and includes four setscrews to lock them into place using a 5/64" (2.0 mm) hex key or balldriver. 

The KC2L(/M) and KC2T(/M) Kinematic Mounts offer three 100 TPI (Threads Per Inch) adjustment screws for smooth, high-resolution movement. Each adjuster is independently locking, and has a collet that can be tightened without causing the position of the adjuster to drift. The rugged mechanical design provides excellent stability when mounted in a cage system or on a post. Both the front and rear plates have been machined with four clearance holes designed for direct compatibility with our 60 mm cage system standards. The rear plate provides locking setscrews to clamp to cage rods for secure positioning. The cage rod holes in the front plate are sufficiently oversized to allow ±3º tip and tilt without interference with the rods.

The KC2L(/M) is designed for thicker optics with a 0.12" (3.0 mm) minimum thickness, while the KC2T(/M) is capable of mounting thin optics not exceeding 0.2" (5.0 mm) thick.

• Mounts Ø2" (Ø50.8 mm) Optics at a 45° Angle to the Optical Axis
• Eight 4-40 Tapped Holes for ER Cage Rods
• Provides ±4º Kinematic Tip and Tilt Adjustment
• 60 mm Cage System and SM2 (2.035"-40) Compatible
• Post Mountable:
  • KCB2: One 8-32 Tap and One 1/4"-20 Tap (for Ø1/2" and Ø1" Posts)
  • KCB2/M: One M4 Tap and One M6 Tap (for Ø1/2" and Ø1" Posts)

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. 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. 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).

• Mounts 2" (50.8 mm) Elliptical Optics at a 45° Angle to the Optical Axis
• Eight 0.195" (5.0 mm) Deep Smooth Bore Holes for ER Cage Rods
• Provides ±3º Kinematic Pitch and Yaw Adjustment

  • KCB2EC/M: One M4 Tap and One M6 Tap (for Ø1/2" and Ø25.0 mm Posts)

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.

Using a BHM6 Ruler and RBP2 Base to Align a KCB2 Mount

The RBP2(/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 KCB2(/M), KCB2C(/M), or KCB2EC(/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 RBP2(/M) post base 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 RBP2(/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 RBP2(/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).
