30 mm Cage Plate for Objectives, Post Mountable
OVERVIEW
Thorlabs offers several RMS-threaded, fixed mounting options for securing microscope objectives. The OT1 Objective Lens Turret enables repeatable positioning of up to four microscope objectives and has an externally SM1-threaded mounting interface. The CP42(/M) Cage Plate can hold a single microscope objective, has an 8-32 (M4) tapped hole for post mounting, and has four through holes for mounting into a 30 mm cage system. The OMR(/M) Objective Mount also holds a single objective with an 8-32 (M4) tap for post mounting.
Microscope Objective Turret, SM1-Compatible
- Four RMS-Threaded (0.800"-36) Objective Lens Ports
- SM1-Threaded (1.035"-40) Mounting Interface
- Bi-Directional Repeatability: ±2.5 µm
The OT1 is a compact objective lens turret with four RMS (0.800"-36)-threaded ports. The aluminum housing has steel inserts at critical points to ensure the durability and precision of the detent mechanism, which reproducibly positions the objective lenses with a high degree of accuracy. The mounting interface for the OT1 objective lens turret has SM1 (1.035"-40) threading so that it can be easily integrated into custom imaging systems built using Thorlabs' Lens Tube and Cage Systems. To mount the OT1 in a cage system, use a CP33(/M) or CP33T(/M) for a 30 mm cage system and an LCP02(/M) for a 60 mm cage system.

CP42 Cage Plate Mounting an RMS-Threaded Objective in a 30 mm Cage System
- Integrates RMS Components with a 30 mm Cage System Assembly
- Tapped with RMS Threading (0.800"-36)
- Post Mountable via 8-32 (M4) Tap
- Thickness: 0.35" (8.9 mm)
The CP42(/M) Cage Plate allows for RMS-threaded components, including many of our microscope objectives, to be incorporated with our 30 mm cage system. Each cage rod through hole is accompanied by a side-located locking M4 setscrew, which can be secured using a 5/64" (2.0 mm) balldriver or hex key. The CP42(/M) can also be post mounted using the 8-32 (M4) threaded hole on the bottom.
We also offer the RMSRR RMS Retaining Ring (not included) for positioning components within the cage plate.
