- 4 RMS-Threaded (0.800"-36) Objective Lens Ports
- SM1-Threaded (1.035"-40) Mounting Interface
- Precision Detent Mechanism for Objective Lens Positioning
The OT1 is a compact objective lens turret with four RMS-threaded ports. The housing is primarily constructed of aluminum but has steel inserts at critical points to ensure the durability and precision of the detent mechanism that reproducibly positions the objective lenses with a bi-directional repeatability of ±2.5 µm.
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 CP02 or CP02T for a 30 mm cage system and an LCP02 for a 60 mm cage system. The OT1 is designed to securely hold objectives in either horizontal or vertical orientations.
