Product Family Description

  • C, S, and T-Mount Solutions for Mounting Cube and Plate Beamsplitters, Filters, and Mirrors
  • Provides a 90° Mounting Interface
  • ¼ -20 and M6 Tapped Mounting Threads for English or Metric Based Systems

TECHSPEC® C, S, and T-Mount Cube and Plate Mounts allow for the integration of cube and plate optics into C, S, and T-Mount systems. These mounts feature four C, S, or T-Mount threaded apertures that can also act as connection points for other C, S, or T-Mount components. Either an M6 or 1/4-20 tapped hole is provided on the base for post mounting, making these mounts compatible with breadboard and benchtop systems. TECHSPEC C, S, and T-Mount Cube and Plate Mounts provide a 90° mounting interface ideal for placing beamsplitters, filters, and mirrors within a system. C, S, and T-Mount Aperture Caps are available to block light from unused openings and to protect the optic from dust and debris.

Note: #11-139 and #11-142 each include one S-Mount Aperture Cap (#11-137)
