Kinematic Mounts for 30 mm Cage Systems

Click to Enlarge

• ±5º Tip / Tilt, ±3 mm Linear Translation Along the Optical Axis
• Accepts Ø1" (25.4 mm) Optics
• Minimum Optic Thickness: 0.12" (3 mm)
• Compatible with 30 mm Cage System
• 8-32 (M4) Tapped Hole for Post Mounting

The KC1 Kinematic Mount is designed with a smooth, double-bored mounting hole that can accommodate a Ø1" optic that is at least 0.12” (3 mm) thick; the optic is held in place with a top-located, nylon-tipped locking screw. This kinematic mount comes with three 1/4-80 adjusters that offer an adjustment per revolution of 7 mrad/rev. In addition, each adjuster has independently locking setscrews.

Both the front and rear plates have been machined with four clearance holes designed for direct compatibility with our 30 mm cage system standard. The cage rod holes in the front plate are sufficiently oversized to allow ±4º tip and tilt adjustment without cage rod interference. Once the desired position is achieved, locking setscrews on the rear plate can be used to secure the rods in place. In addition to 30 mm cage compatibility, the KC1 is post mountable via an 8-32 (M4) tapped hole.

• ±5º Tip / Tilt, ±3 mm Linear Translation Along the Optical Axis
• Accepts Ø1" (25.4 mm) Optics
• Maximum Optic Thickness: 0.23" (5.8 mm)
• Compatible with 30 mm Cage System
• 8-32 (M4) Tapped Hole for Post Mounting

The KC1-T Kinematic Mount is designed with an SM1-threaded (1.035"-40) mounting hole that can directly hold optics up to 5.8 mm (0.23”) thick using the two included SM1RR Retaining Rings. Thicker optics can be accommodated by housing the optic in one of our SM1-Series Lens Tubes and then threading the lens tube into the front plate of the mount. Alternatively, since the back plate of the KC1-T features an oversized Ø1.32" bore, SM1 lens tubes can also be attached to the front plate from the rear of the mount without sacrificing angular adjustment. This threaded, kinematic mount comes with three adjusters with independently locking setscrews.

Both the front and rear plates have been machined with four clearance holes designed for direct compatibility with our 30 mm cage system standard. The cage rod holes in the front plate are sufficiently oversized to allow ±4º tip and tilt adjustment without cage rod interference. Once the desired position is achieved, locking setscrews on the rear plate can be used to secure the rods in place. In addition to 30 mm cage compatibility, the KC1-T is post mountable via an 8-32 (M4) tapped hole.

KC1-P Optic Mount

• Smooth Bore or SM1-Threaded Versions Available
• Manual and Piezo Adjusters in Series
• Accepts Ø1" (Ø25.4 mm) Optics
• Compatible with 30 mm Cage Systems
• 8-32 (M4) Taps for Post Mounting

These kinematic mirror mounts incorporate piezo-driven fine adjustment into our KC1 and KC1-T mirror mounts (available above). Each of the three adjustable axes consists of a manual and piezo adjuster in series. The smooth bore versions secure the mirror with a nylon-tipped 8-32 (M4) setscrew, while the SM1-threaded versions secure the mirror with two included SM1RR Retaining Rings. The KC1-PZ(/M) and KC1-T-PZ(/M) offer a piezo linear travel of ±4 µm and minimum step size of 0.3 µrad, while the KC1-P(/M) and KC1T-P(/M) offer a piezo linear travel of ±9.7 µm with minimum step size of 0.37 µrad per 0.1 V step.

The piezo adjusters connect to a controller using the included 3' (91.4 cm) cables, and the maximum control voltage is 150 V. The KC1-PZ(/M) and KC1-T-PZ(/M) mounts include permanently attached BNC cables, while the KC1-P(/M) and KC1T-P(/M) include detachable cables. The KC1-PZ(/M) and KC1-T-PZ(/M) mounts are also sold bundled with the MDT693B Three-Channel Piezo Controller, providing all the components needed for open-loop control of the mount. 

These mounts are 30 mm cage system compatible; the cage rods can be locked into place using their locking screws. They are also post mountable using one of the three 8-32 (M4) mounting taps.

• Slip Plate Provides ±1 mm of Coarse X and Y Adjustment
• ±4º Tip / Tilt, ±3 mm Linear Translation Along the Optical Axis
• Accepts Ø1" Optics
• Maximum Optic Thickness: 0.23" (5.8 mm)
• Compatible with Our 30 mm Cage Systems
• 8-32 (M4) Tapped Hole for Post Mounting

The KC1-S Kinematic Mount is designed with a SM1 (1.035"-40) threaded mounting hole with a front slip plate that enables direct mounting of optics up to 5.8 mm (0.23”) thick using the included SM1RR Retaining Rings. Thicker optics can be accommodated by housing the optic in one of our SM1-Series Lens Tubes and then threading the lens tube into the front plate of the mount. Alternatively, since the back plate of the KC1-S features an oversized Ø1.32" bore, SM1 lens tubes can also be attached to the front plate from the rear of the mount without sacrificing angular adjustment. This threaded, kinematic mount comes with three adjusters with independently locking setscrews.

Both the front and rear plates have been machined with four clearance holes designed for direct compatibility with our 30 mm cage system standard. The cage rod holes in the front plate are sufficiently oversized to allow ±4° tip and tilt adjustment without cage rod interference. Once the desired position is achieved, locking setscrews on the rear plate can be used to secure the rods in place. In addition to 30 mm cage compatibility, the KC1-S is post mountable via an 8-32 (M4) tapped hole.

The KC1-S slip plate feature incorporated into this mount provides ±1 mm of coarse travel in X and Y with respect to the front plate, which enables additional freedom when setting an optic's position within a cage system. Three locking screws allow the user to lock the slip plate down once the desired location has been reached. The user should note, however, that loosening the locking screws may result in excessive coarse movement (slop) in the slip plate. For best performance, tighten the locking screws, and then release them only enough to allow for smooth operation of the slip plate.

• Quick, Drop-In Beam Alignment Tool
• Small Through Hole Aligned at Center of 30 mm Cage Assembly

The CPA1 and CPA2 Alignment Plates are convenient tools for aligning cage-based optical systems. These drop-in plates feature a small through hole at the exact center of the 30 mm cage assembly that is used for aligning visible beams. For easy alignment, the through hole is surrounded by engraved rings, which indicate Ø4 mm, Ø7 mm, Ø10 mm, and Ø13 mm. The CPA1 provides a Ø0.9 mm through hole, while the CPA2 provides a Ø5 mm through hole.

The VRC4CPT and VRC6SCPT Alignment Plates are specifically designed to align IR or MIR beams in a cage-based optical assembly. Both plates are identical to the CPA1 (shown to the left) on the front. The back (shown to the right) of the VRC4CPT includes a Ø1/2" (Ø12.7 mm), non-rotating IR-sensitive fluorescing alignment disk made of the same material used in our VRC4 Viewing Card. Alternatively, the back of the VRC6SCPT includes a Ø0.39" (Ø10.0 mm), non-rotating MIR alignment disk is made of the same thermochromic liquid crystal material used in our VRC6S Viewing Card, which reacts to laser sources over the 1.5 to 13.2 µm wavelength range, and has a minimum detectable power density of 0.05 mW/mm² at 1550 nm (22 °C). The VRC4CPT plate has a Ø1.5 mm hole centered on the plate's Ø0.9 mm hole, and the VRC6SCPT has a Ø2.0 mm hole centered on the plate's Ø0.9 mm hole.
