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

• 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).

• Eight 4-40 Tapped Holes for ER Cage Rods
• Provides ±4° Kinematic Pitch and Yaw Adjustment
• Z-Axis Translation Using All Three Adjusters: ±0.12" (±3.0 mm)

• Post Mountable:
  • KCB1E: One 8-32 Tap and One 1/4"-20 Tap (for Ø1/2" and Ø1" Posts)
  • KCB1E/M: One M4 Tap and One M6 Tap (for Ø1/2" and Ø25.0 mm Posts)

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 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 for a 6 mm thick optic. We offer dielectric and metallic elliptical mirrors, which are compatible with these mounts.

KCB1EC(/M) Mounts have Smooth Bores for Cage Rods

• Mounts 1" (25.4 mm) Elliptical Optics at a 45° Angle to the Optical Axis
• Eight 0.25" (6.35 mm) Deep Smooth Bore Holes for ER Cage Rods
• Provides ±4° Kinematic Pitch and Yaw Adjustment
• Z-Axis Translation Using All Three Adjusters: ±0.12" (±3.0 mm)
• 30 mm Cage System and SM1 (1.035"-40) Compatible
• Post Mountable:
  • KCB1EC: One 8-32 Tap and One 1/4"-20 Tap (for Ø1/2" and Ø1" Posts)

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 ERSCB 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 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.
