Product Details

  • 360° Continuous Optic Rotation
  • 25.4mm Centerline Height
  • 5° Graduations

TECHSPEC® Rotation Kinematic Mounts provide precision control when positioning an optical element. These mounts utilize 100 TPI adjustment screws to offer precise motion control with a tip/tilt range of ±5 arcmin. Continuous 360° optic rotation is achieved through a custom designed optic cell and Teflon ring subassembly. TECHSPEC® Rotation Kinematic Mounts employ retainer ring mounting for evenly distributed pressure on the optics circumference. Available for 25.4mm and 12.7mm diameter optics, these components provide a convenient method for cylinder lens or polarizer optic mounting.
