Optical Coherence Tomography (OCT) is a noninvasive optical imaging technique that produces real-time, 2D cross-sectional and 3D volumetric images of a sample. This technique provides structural information about the sample based on light backscattered from different layers of material within that sample, producing images with micron-level resolution and millimeters of imaging depth. OCT imaging can be considered as an optical analog to ultrasound imaging that achieves higher resolution at the cost of decreased penetration depth. In addition to high resolution, the non-contact, noninvasive nature of OCT makes it well suited for imaging samples such as biological tissue, small animals, and industrial materials.
Thorlabs' Ganymede™ Series of OCT Imaging Systems provide the flexibility required for high-resolution imaging applications with A-scan line rates up to 248 kHz. The 64-bit software pre-installed on the included computer displays and processes 2D and 3D OCT data in real time. Choose from a number of scanner options including a robust standard scanner, user-customizable scanner, and the portable handheld scanner. Optional accessories are available below to customize your OCT system to meet the requirements of your application. Additionally, Thorlabs offers five complete, preconfigured OCT systems operating with 880 nm, 930 nm, or 900 nm center wavelengths based on the components sold on this page.
The components below can also be used to upgrade your existing Thorlabs OCT system with additional features and are fully compatible out of the box with Thorlabs' OCT systems and accessories. While most systems are upgradable, we recommend contacting the

ThorImageOCT is a high-performance data acquisition software that is included with all Thorlabs OCT systems. This 64-bit Windows-based software acquires and displays OCT data, as well as includes scan control and processing options. Additionally, NI LabVIEW and C-based Software Development Kits (SDKs) are available, which contain a complete set of libraries for measurement control, data acquisition, and processing, as well as for storage and display of OCT images. The SDKs provide the means for developing highly specialized OCT imaging software for every individual application.
OCT Family Updates
We recently improved the OCT Base Units, and the new additions include:
- Fully Configurable Trigger for Integration into Larger Experiments
- Analog Input for Combining Other Data Sources with the OCT Signal
- Internal Hardware Diagnostics for Improved Troubleshooting
The SD-OCT standard scanners have also been redesigned with a new micrometer screw for more precise reference arm positioning.
New features added to ThorImage®OCT include a despeckle filter, 3D speckle variance mode, and automatic peak detection.

Thorlabs offers five complete, preconfigured Ganymede OCT systems, each of which is fully compatible with all Ganymede Series OCT components. The GAN111C1 system operates at 880 nm center wavelength and offers high-resolution imaging capability. The GAN311C1 and GAN611C1 configurations feature a center wavelength of 930 nm and are ideal for high-speed, high-resolution imaging applications. Operating at 900 nm center wavelength, the GAN621C1 and GAN321CI systems are designed for high-speed imaging applications requiring very high resolution. The Ganymede systems have an A-scan rate of up to 248 kHz and 106 dB sensitivity at 1.5 kHz.
These Ganymede Series preconfigured OCT system configurations are built completely from components sold in sections located lower on this page. Each preconfigured system includes the three OCT system core components (the base unit, a scanning system with its reference length adapter, and a scan lens kit), as well as two optional accessories (scanner stand and translation stage).
