OEM OCT Imaging Systems

Hide Overview


2D and 3D Imaging Solutions for Structural Analysis

Thorlabs offers engineering solutions for integrating customized Optical Coherence Tomography (OCT) imaging modules into complex host systems. At our facilities in Lübeck, Germany and Newton, NJ, we manufacture these systems and their components. We look forward to working with you to design a custom system that meets your needs.

This page is designed to provide insight into the tried and true processes that make Thorlabs the ideal choice for OEM systems. We evaluate every OEM opportunity using a finely tuned process developed by our experienced engineering team. This process is detailed on the Engineering Process tab. The Technology and Implemented Projects tabs detail the advantages and limitations of OCT technology and highlight various fields in which Thorlabs has successfully designed and manufactured OCT system solutions. More information about our engineering team and the company as a whole can be found on the Thorlabs' Expertise tab.

Project Considerations

To successfully integrate advanced imaging technology into a complex host system, there are many factors to consider beyond component development:

  • Selection of the best-suited parameters for the imaging technology within the context of the host system and its application
  • A dedicated engineering team that is in close contact with the host system development team
  • Customization of certain components for seamless host system integration
  • A reliable manufacturing process that provides timely delivery of high-quality components

Optical Coherence Tomography

Optical Coherence Tomography (OCT) is a high-resolution, cross-sectional imaging technology that analyzes echoes of backscattered light from layers of microstructures close to the surface of the sample (i.e., up to several millimeters deep). This low coherence, interferometric technology generally employs near infrared light and offers a spatial resolution of 1 - 15 µm, which is one to two orders of magnitude higher than conventional ultrasound. It can generate real-time, volumetric data at video frame rates.

OCT is commonly used for in vivo analysis of biological tissues but is expanding into other domains such as non-destructive material inspection. Currently, OCT is an established technique often used in medical imaging systems, offering a level of precision and reliability that was not possible before.

Thorlabs' OCT group in Lübeck, Germany specializes in the development of Spectral Domain OCT engines, while our group in Newton, NJ has expertise in the development of Swept Source OCT components and systems, including a new MEMS-Tunable VCSEL Swept Source Laser Source offering single mode, mode-hop-free operation over a tuning range in excess of 100 nm.
