  • Two Retaining Rings Included for Mounting Optic
  • Compatible with 16 mm Cage Systems
  • Ideal for Use with Unmounted Aspheric and Achromatic Lenses
  • Not Post Mountable

These cage plates have internal threads and are designed for mounting optics that have diameters from 5 mm up to 12 mm, such as our unmounted aspheric and achromatic lenses, into a 16 mm cage system. Two retaining rings of the appropriate size are included with each cage plate and are used to secure the optic. The SPW801 spanner wrench is recommended when threading the retaining rings into place. Each plate features four corner-located, Ø4 mm through-holes with a center-to-center spacing of 16 mm. These holes are machined for a precision slip fit with mating cage rods and provide side-accessible locking 4-40 setscrews, which can be secured to a cage rod using a 0.05" hex keyIn addition, four 3-48 cap screws (not included) can be used to bolt the cage plate onto the SC6W six-way cage cube. 

Thorlabs also offers internally threaded, post-mountable fixed mounts , which are not cage compatible, for mounting optics from Ø5 mm to Ø4".
