Product Family Description

  • Available for a Range of Optical Lens Diameters
  • Adds Additional Adaptability to Cage System
  • Retaining Ring Included

TECHSPEC® Cage System Optical Lens Mounts, constructed of anodized aluminum, are designed to be used in a two-step process. First, secure the optical component within the lens mount using the included retaining ring. Second, secure the lens mount within the inner diameter of a cage system plate. By enabling the addition and removal of lens mounts from plates, the system creates a wide range of flexibility for cage setups. TECHSPEC Cage System Optical Lens Mounts are ideal as stand-alone components or combined with cage system tubes.

Note: #85-678 is a two-piece assembly that can be used with either 25mm or 30mm cage system plates. Replacement retaining rings are sold separately.
