Microscope Objective Turret, SM1 Compatible

• Four RMS-Threaded (0.800"-36) Objective Lens Ports
• External SM1 Threads (1.035"-40) on Mounting Interface
• Precision Detent Mechanism for Objective Lens Positioning

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 bi-directional repeatability of ±2.5 µm. The mounting interface for the OT1 objective lens turret has external 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 turret in a cage system, use a CP33(/M) for a 30 mm cage system or an LCP33(/M) for a 60 mm cage system.

RMSCP1 Covering an Objective

• RMSCP1: Internally RMS-Threaded Cap for Microscope Objectives
• RMSCP2: Externally RMS-Threaded Cap for Objective Lens Turret Ports

These RMS-Threaded Caps are designed to protect microscope objectives, objective lens turret ports, and other RMS (0.800"-36) threaded components. The RMSCP1 has internal RMS threading, making it compatible with standard RMS-threaded microscope objective lenses. The RMSCP2 has external RMS threading to cover unused objective lens ports (see image on the far right). Each of these caps is made from anodized aluminum and has a knurled edge for secure hand tightening.
