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.

請問寬度以及長度在20mm 厚度在2mm左右的薄板時否也可以裝在這個治具內,以利後續作調整?

Thank you for reaching out to us with this inquiry. You are specifically asking about mounting a square optic with 20mm sides and a thickness of 2mm. Unfortunately this product is designed for the following dimensions: 25x36x1mm and 25x50x≥3mm. Perhaps you would be more interested in something from this page:, such as the KM100C.
