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.
