Kinematic Mounts for 60 mm Cage Systems

• Mounts Ø2" (Ø50.8 mm) Optics on the Optical Axis
• Through Holes for ER Cage Rods
• Provides ±3° Kinematic Tip and Tilt Adjustment
• KC2 Secures Optics with a Nylon-Tipped Setscrew
• KC2-T is SM2-Threaded (2.035"-40) and Includes 2 SM2RR Retaining Rings
• Post Mountable: Three 8-32 (M4) Tapped Holes

Our KC2(/M) and KC2-T(/M) Mounts provide kinematic tip and tilt adjustment of a Ø2" (Ø50.8 mm) optic. The KC2(/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 0.050" hex key or balldriver. The ±3° kinematic tip and tilt adjustment is actuated with three 100 TPI (Threads Per Inch) adjustment screws for smooth, high-resolution movement. These adjusters feature a locking collar design and removable knobs.

The KC2(/M) is designed for thicker optics (0.12" minimum thickness), while the KC2-T(/M) is capable of mounting thin optics (not exceeding 0.2" 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).

• Mounts Ø2" (Ø50.8 mm) Optics at a 45° Angle to the Optical Axis
• Eight 0.20" (4.95 mm) Deep Smooth Bore Holes for ER Cage Rods
• Provides ±4º Kinematic Tip and Tilt Adjustment
• 60 mm Cage System and SM2 (2.035"-40) Compatible
• Post Mountable:
  • KCB2C: One 8-32 Tap and One 1/4"-20 Tap (for Ø1/2" and Ø1" Posts)
  • KCB2C/M: One M4 Tap and One M6 Tap (for Ø1/2" and Ø1" Posts)

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).

The mirror is locked in place by a swing arm and nylon-tipped setscrew. The adjuster knobs feature side holes for fine adjustments.

• 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
• Z-Axis Translation Using All Three Adjusters: ±0.12" (±3.0 mm)
• 60 mm Cage System and SM2 (2.035"-40) Compatible
• Post Mountable:
  • KCB2EC: One 8-32 Tap and One 1/4"-20 Tap (for Ø1/2" and Ø1" Posts)
  • 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.
