The C1503/M is a Kinematic V-Clamp Mount that provides two axes of precision angular adjustment. This clamp is ideal for mounting a HeNe laser or other large cylindrical objects. The angular adjustments provide control of the beam pointing, while the vertical height can be set by moving the unit along the support post (P-series Post). A series of hardened chromium steel balls and ball seats form a true kinematic mechanism that works with gravity and heavy duty springs to provide long-term stability. Vertical positioning is achieved by sliding the rear clamping mechanism along the length of the Ø1.5" post. The clamping mechanism is actuated with a 5 mm Allen key or balldriver.
