Figure G1.1  PF03-03-P01 7 mm Optic Mounted in an MK7 Kinematic Mirror Mount

• Mounts Ø7 mm Optics at Least 0.04" (1.00 mm) Thick
• Compact Nominal Footprint: 0.79" x 0.52" (20.0 mm x 13.2 mm)
• Resolution: 13.4 mrad/rev (0.76°) per Revolution via Two M2.5 x 0.20 Precision Adjusters
• 4-40 (M3) Mounting Holes Allow for Left- or Right-Handed Orientation

Thorlabs' MK7(/M) Mini-Series Kinematic Mirror Mount is designed to mount Ø7 mm optics in optomechanical setups where space is a premium. The optic can be adjusted using two M2.5 x 0.20 adjuster screws that accept a 0.050" (1.3 mm) hex key (not included), each having a resolution of 13.4 mrad/rev (0.76°) per revolution.

• Mounts Ø10 mm Optics at Least 0.04" (1.00 mm) Thick
• Compact Nominal Footprint: 0.79" x 0.52" (20.0 mm x 13.2 mm)
• Resolution: 13.4 mrad/rev (0.76°) per Revolution via Two M2.5 x 0.20 Precision Adjusters
• 4-40 (M3) Mounting Holes Allow for Left- or Right-Handed Orientation

Thorlabs' MK10(/M) Mini-Series Kinematic Mirror Mount is designed to mount Ø10 mm optics in optomechanical setups where space is a premium. The optic can be adjusted using two M2.5 x 0.20 adjuster screws that accept a 0.050" (1.3 mm) hex key (not included), each having a resolution of 13.4 mrad/rev (0.76°) per revolution.

Optics compatible with the MK10(/M) include our AL108, AL108-A, AL108-B, AL108-C Ø10 mm CNC-polished aspheric lenses, as well as our ACL108U, ACL108U-A, and ACL108U-B Ø10 mm aspheric condenser lenses.

Figure G3.1  Size Comparison between Our Ø1/2" KM05 (Left) and Ø1/2" MK05 (Right) Kinematic Mirror Mounts

• Mounts Ø1/2" Optics at Least 0.12" (3.05 mm) Thick
• Compact Nominal Footprint: 0.79" x 0.52" (20.0 mm x 13.2 mm)
• Resolution: 13.4 mrad/rev (0.76°) per Revolution via Two M2.5 x 0.20 Precision Adjusters
• 4-40 (M3) Mounting Holes Allow for Left- or Right-Handed Orientation

Thorlabs' MK05(/M) Mini-Series Kinematic Mirror Mount is designed to mount Ø1/2" and 12.5 mm optics in optomechanical setups where space is a premium. The optic can be adjusted using two M2.5 x 0.20 adjuster screws that accept a 0.050" (1.3 mm) hex key (not included), each having a resolution of 13.4 mrad/rev (0.76°) per revolution. As shown in Figure G3.1, it is significantly more compact than our KM05(/M) Ø1/2" Kinematic Mirror Mount.

Figure 642A  MK05 Mini-Series Kinematic Mirror Mount with HKTS-050 Thumbscrew

• For Convenient Adjustment of 0.050" Hex-Driven Actuators
• Red, Anodized Adjustment Knob with Engraved Hex Size
• Replaceable Hex Tip
• Sold in Packs of 4

Hex Key Thumbscrews allow for quick, low-profile adjustment of hex-driven actuators, cap screws, and setscrews. Unlike balldrivers, they can be left in the screw's hex socket between adjustments for convenience. The 0.050" size is especially useful for adjusting our imperial, hex-driven, mini-series kinematic mirror mounts, sold above, as well as any 4-40-sized screws, such as the setscrews on our 30 mm cage plates.

Additional hex key thumbscrews are available in sizes from 1/8" to 3/16" and 2 mm to 5 mm.

Figure 643A  A single locking collar can lock an adjuster's position with an SPW403 spanner wrench.

• Extremely Compact Lock Nut: 0.07" (1.7 mm) Thick
• Use One Collar To Lock an Adjuster to a Bushing
• Use Two Collars to Create a Hard Stop on an Adjuster
• Locking Collars Sold in Packs of Five
• Install and Remove with the SPW403 Spanner Wrench

These locking collars are only 0.07" (1.7 mm) thick and are constructed of 303 stainless steel. They are compatible with the M2.5 x 0.20 adjusters on our Mini-Series Kinematic Mirror Mounts, Mini-Series Kinematic Mount for Cylindrical Components, and our FiberBench and Post-Mountable Kinematic Tip/Tilt and Rotation Mounts.

The locking collars can be used to lock an adjuster in a desired position, or to create a hard stop at any position to prevent overdriving an adjuster. In addition to using two collars to create a hard stop, a single collar can be epoxied to an adjuster using our G14250 epoxy to create a permanent hard stop. We recommend the SPW403 Spanner Wrench to install or remove these locking collars. The end of the SPW403 is machined to accept a 5/64" hex wrench, which can be used to provide additional torque. The hollow cylindrical construction of the SPW403 allows a tool to pass through the entire length of the spanner wrench and access the adjuster.
