The highly stable, compact KM05 and KM05/M mirror mounts are ideal for OEM applications. A setscrew secures the mirror along the two lines of contact created by a double bore. The two actuators utilize a hex socket to minimize accidental movement in shared facilities.

The KM05 features 3/16"-100 adjusters for tip and tilt adjustments. An optional accessory, the LN19100 bronze locking nut, is available to lock the adjusters once the desired position is reached.

The KM100 is our most popular Ø1" mirror mount. This mount is imperial/metric compatible and equipped with heavy-duty springs to ensure an ultra stable design. The optic is secured in a 0.3" (7 mm) deep cavity with a nylon-tipped locking screw (replacement item: SS8N013). The KM100 features 1/4"-80 adjusters for tip and tilt adjustments. An optional accessory, the LN2580 bronze locking nut, is available to lock the adjusters once the desired position is reached. For your convenience, the KM100 is stocked for same-day shipment with your choice of four different broadband dielectric mirrors (see table at left).

• Mounts Thin Ø1" Optics up to 0.14" (3.6 mm) Thick
• Optics Held with Retaining Ring
• Angular Range: ±4°
• Resolution: 8 mrad (0.5°) per rev via Two 1/4"-80 Precision Adjusters
• Two Counterbored #8 (M4) Through Holes Allow for Left- or Right-Handed Orientation
• Removable Knobs Expose Hex Sockets in Lead Screws
• Ø1" Lens Tube Compatible via SM1 Threading

The KM100T mirror mount uses a retaining ring for stress-free mounting of a thin optical component. An optic is secured in the mounting hole with the included SM1RR SM1 (1.035"-40) threaded retaining ring, which can be attached using the SPW602 spanner wrench. This threading also allows the mount to be compatible with Ø1" lens tubes.

The universal KM100T is compatible with both imperial and metric threaded Ø1/2" mounting posts via #8 (M4) counterbored through holes and can be attached to the post in either a right- or left-handed orientation. The mount has removable knobs that expose hex sockets in the lead adjuster screws. The KM100T features 1/4"-80 adjusters for tip and tilt adjustments. An optional accessory, the LN2580 bronze locking nut, is available to lock the adjusters once the desired position is reached.

Thin Kinematic Mounts are also suitable for mounting fiber collimators utilizing adapters such as the AD11F, as shown above.

The KM100CP places the optic's front surface over the center of the post.

• Front Surface of Mirror Aligned with Post-Mounting Hole to Simplify Beam Alignment
• Rear Loaded Double-Bored Mounting Cell with Nylon-Tipped Set Screw Secures Optic
• Mounts Ø1" Optics at Least 0.12" (3 mm) Thick

The KM100CP Ø1" kinematic mirror mount is designed to center the front surface of a mirror over the center of the mounting post. The mount can be attached to either a Ø1/2" post or Ø1" (Ø25 mm) post via the mount's 8-32 (M4) tapped hole. If the mirror's front surface is aligned over one of the breadboard's holes, a beam incident at 45° can be easily aligned with the table's hole matrix. The mount is attached to the post via one of two tapped holes, which allow for right- or left-handed adjuster orientation.

The unique design of the KM100CP incorporates the post-mounting feature into the fixed, rear plate of the mount, which is also where the brass bushings are found. By having the bushings in the fixed plate, as opposed to the movable plate, the instability of the mount is greatly reduced during adjustments.

As with our standard KM100 mounts, our post-centering mount is designed with two 1/4"-80 adjusters that yield ±4° of angular adjustment, and a resolution of 8 mrad (0.5°) per revolution. An optional accessory, the LN2580 bronze locking nut, is available to lock the adjusters once the desired position is reached. The mirror is locked in place with a nylon-tipped locking screw that can be tightened with a 5/64" hex key or balldriver. While our standard KM100 mount centers the optic 1" (25.4 mm) above the post, the KM100CP centers the optic 1.25" (31.8 mm) above the post due to the design of the post mounting feature.

The KMCP adapter can also be used to center our standard KM100 mount over the center of a Ø1/2" post.
