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.
