MK05S Kinematic Mount Shown with 1/2" Square Mirror

• Hold 1/2" Tall Square or Rectangular Optics
• ±4° Tip/Tilt Adjustment Range
• High Resolution:
  • MK05S(/M): 13.4 mrad per Adjuster Revolution
  • KM05S(L)(/M): 13 mrad per Adjuster Revolution
• Post Mounting Features:
  • MK05S(/M): Two 4-40 (M3) Taps for Mini-Series Posts
  • KM05S(L)(/M): Two 8-32 (M4) Taps for Ø1/2" Posts

The MK05S(/M) Mini-Series Kinematic Mount holds 1/2" tall rectangular optics that are at least 2.54 mm (0.10") thick, such as metallic or dielectric mirrors and diffraction gratings. The optic is secured with a nylon-tipped 0.050" (1.3 mm) hex setscrew. The setscrew and bottom of the mount provide three points of contact for stable mounting. This mount has two 4-40 (M3) threaded holes that enable horizontal or vertical mounting. This two-adjuster mount does not come with adjuster knobs, making it ideal for use in confined spaces. The M2.5 x 0.20 adjusters are actuated with a 0.050" (1.3 mm) hex key, such as our HKTS-050 Hex Key Thumbscrews. The angular displacement range of the mirror face is ±4° with an adjustment of 13.4 mrad (0.76°) per revolution. An optional accessory, the F10SC1-5 Locking Collar, is available to lock the M2.5 x 0.20 adjusters once the desired position is achieved. We also offer Mini-Series mounts for round mirrors.

The KM05S(/M) and KM05SL(/M) Standard Mounts secure 1/2" rectangular optics that are at least 3.0 mm (0.12") thick using a nylon-tipped 5/64" (2.0 mm) hex setscrew and a flexure clamp mechanism. The setscrew presses the flexure clamp against the edge of the optic to create an area of contact, holding the optic securely in the mount. The KM05S(/M) and KM05SL(/M) are right- and left-handed mounts, respectively. Each mount has two 8-32 (M4) tapped holes for mounting to our Ø1/2" posts. These mounts do not come with adjuster knobs, making them ideal for use in confined spaces. The 3/16"-100 adjusters are actuated with a 5/64" (2.0 mm) hex key, such as our HKTS-5/64 Hex Key Thumbscrews (sold below). An optional accessory, the F19SC1 Locking Collar, is available to lock the 3/16"-100 adjusters once the desired position is achieved.

The KM2536 mount can hold 25 mm x 50 mm optics at least 3 mm thick, like the GE2550-0363 Diffraction Grating shown here.

• Secure 1 mm Thick, 25 mm x 36 mm Optic with Spring Clips on the Back of the Front Plate
• Mount ≥3 mm Thick, 25 mm x 50 mm Optic in the Front of the Front Plate Using Nylon-Tipped Setscrew
• 1.85" x 1.00" Elliptical Clear Aperture
• ±3° Tip/Tilt Adjustment Range
• 8 mrad per Adjuster Revolution
• Compatible with our Ø1/2" Posts

The KM2536 Kinematic Mount features a front plate that can hold both a 25 mm x 36 mm optic that is 1 mm thick and a 25 mm x 50 mm rectangular optic that is ≥3 mm thick. To secure the 25 mm x 36 mm optic without introducing excessive stress, the back of the front plate has a mounting frame with spring-loaded clamps that can be adjusted using a 0.050" (1.3 mm) ball driver or hex key. This is ideal for mounting 25 mm x 36 mm dichroic, non-polarizing, and polarizing beamsplitters. Optics 3 mm or thicker, such as 25 mm x 50 mm diffraction gratings, can be secured on the front side of the front plate using a nylon-tipped, 5/64" (2.0 mm) hex setscrew.

The mount features two removable 1/4"-80 adjuster knobs for ±3° of tip/tilt. Tip/tilt can also be adjusted with a 5/64" (2.0 mm) hex key or ball driver. Two #8 (M4) clearance holes enable horizontal or vertical mounting. An optional accessory, the LN2580 Bronze Locking Nut, is available to lock the 1/4"-80 adjusters once the desired position is reached. We also offer the F25SSK1L Large-Diameter Knob for finer actuator control and the PIAK10 Piezo Inertia Actuator for high-resolution motorized control.

These kinematic mounts are designed to hold 1" tall rectangular optics that are at least 3.0 mm (0.12") thick, such as metallic or dielectric mirrors and diffraction gratings.   

The KMSR(/M) Compact Mount features a compact design in which the optic is secured with a nylon-tipped 5/64" (2.0 mm) hex setscrew, as shown in the photo to the right. The setscrew and bottom of the mount provide three points of contact for stable mounting. This mount has two 8-32 (M4) threaded holes that enable horizontal or vertical mounting. This two-adjuster mount does not come with adjuster knobs, making it ideal for use in confined spaces. The 3/16"-100 adjusters are actuated with a 5/64" (2.0 mm) hex key, such as our HKTS-5/64 Hex Key Thumbscrews (sold below). The angular displacement range of the mirror face is ±4° with an adjustment of 15 mrad per revolution. An optional accessory, the F19SC1 Locking Collar, is available to lock the 3/16"-100 adjusters once the desired position is achieved. We also offer versions of this mount for round mirrors.

The KM100S and KM100SL Mounts secure 1" rectangular optics that are at least 3.0 mm (0.12") thick using a nylon-tipped 5/64" (2.0 mm) hex setscrew and a flexure clamp mechanism. The setscrew presses the flexure clamp against the edge of the optic to create an area of contact, holding the optic securely in the mount. The KM100S mount is right handed, while the KM100SL is left handed. They feature two 1/4"-80 adjusters and include one 8-32 cap screw and one M4 cap screw for mounting to our Ø1/2" posts. An optional accessory, the LN2580 Bronze Locking Nut, is available to lock the 1/4"-80 adjusters once the desired position is reached. We also offer the F25SSK1L Large-Diameter Knob for finer actuator control and the PIAK10 Piezo Inertia Actuator for high-resolution motorized control.

• Compatible with Our Ø1/2" Posts

Our KM200S(L) Mounts hold 2" tall square or rectangular optics that are at least 3.0 mm (0.12") thick. We recommend these mounts for holding our square metallic or dielectric mirrors and diffraction gratings. The KM200S mount is right handed, while the KM200SL is left handed. The optic is secured in each mount with a nylon-tipped 5/64" (2.0 mm) hex setscrew and a flexure clamp mechanism. The setscrew presses the flexure clamp against the edge of the optic to create an area of contact, holding the optic securely in the mount. It features two 1/4"-80 adjusters for tip/tilt adjustment and six #8 (M4) counterbored holes for mounting to our Ø1/2" posts. One 8-32 cap screw and one M4 cap screw are included with the mount. An optional accessory, the LN2580 Bronze Locking Nut, is available to lock the 1/4"-80 adjusters once the desired position is reached. We also offer the F25SSK1L Large-Diameter Knob for finer actuator control and the PIAK10 Piezo Inertia Actuator for high-resolution motorized control.

KM100C Mount with 50 mm Tall Cylindrical Lens Using Additional ER Rods

• Adjustable Clamping Arm Capable of Mounting Optics up to 1.3" (33.0 mm) Tall
• Mounts Optics up to 65 mm Wide
• Tip/Tilt Adjustment Range of ±4°, 8 mrad per Adjuster Revolution
• Two #8 (M4) Counterbores at 90° in Back Plate Enable Post Mounting
• Right- and Left-Handed Configurations Available
• Rubber Pads Increase Contact Area with Optic

The KM100C(L) Adjustable-Height Mounts are ideal for mounting cylindrical lenses of various sizes. They are available in right-handed (item # KM100C) or left-handed (item # KM100CL) configurations. Optics are securely held in place by two rubber-padded arms that can be locked with a 0.05" hex key. The length of the rubber pads is 0.79" (20.0 mm) and we recommend mounting optics with an edge thickness no greater than 0.3" (7.62 mm). Mounting larger optics may affect the stability and performance of the mounts.

The mount accepts cylindrical optics up to 1.3" (33.0 mm) tall. The adjustable clamping arm is mounted to two preinstalled ER1.5 rods. To accommodate taller optics, additional ER rods (sold separately) can be screwed onto those included with the mount (as seen in the photo to the right). It also has two #8 (M4) counterbores for mounting to our Ø1/2" posts.

The kinematic tip/tilt adjustments, driven by two 1/4"-80 adjusters, simplify positioning. An optional accessory, the LN2580 Bronze Locking Nut, is available to lock the adjusters once the desired position is reached.
