GANYMEDE 930 nm OCT System


Ganymede 930 nm OCT System

  • Cross-Sectional and Volumertic Imaging


Thorlabs' GANYMEDE™ OCT Imaging System


  • A-Scan Rate of Up to 30 kHz
  • General-Purpose OCT System with Video-Rate Imaging Speed
  • Three Acquisition Modes for Flexibility in Imaging Speed and Sensitivity
  • Ideal for Biological and Industrial Materials Imaging Applications
  • Large Field of View: 10 mm x 10 mm x 2.7 mm
  • Custom Configurations Available

Thorlabs' GANYMEDE™ OCT Imaging System offers three acquisition speed settings. In the High Speed mode with 30 kHz A-Scan rate, 1024 x 1024 pixel images can be displayed in video rate and with 91 dB sensitivity. In contrast, the High Sensitivity Mode provides the ability to record images with a sensitivity of up to 106 dB at 1.25 kHz A-Scan rate. Increasing sensitivity, at the cost of imaging speed, enables higher contrast during imaging, thereby improving detection of very weakly resolved structures in the sample. The GANYMEDE Spectral Domain OCT System is an excellent general-purpose system for imaging biological samples as well as producing 2D cross-sectional images and 3D volume datasets.

The GANYMEDE utilizes a GigE data connection and is controlled via software preinstalled on a high-performance computer that is capable of online rendering and display of all measured 3D datasets. It also includes a 3D scanning, common path probe with integrated video camera for volume imaging and live video display. The included stand and sample stage provide XY translation and rotation of the sample along with axial travel of the probe. The GANYMEDE system is fully functional right out of the box.

Optical Coherence Tomography (OCT) is a noninvasive optical imaging modality that provides real-time, 1D depth, 2D cross-sectional, and 3D volumetric images with micron-level resolution and millimeters of imaging depth. OCT images provide structural information of a sample, based on light backscattered from different layers of material within that sample. OCT imaging is considered to be the optical analog to ultrasound. OCT, however, achieves higher resolution through the use of near infrared wavelengths, at the cost of decreased penetration depth. In addition to high resolution, the non-contact, noninvasive advantage of OCT makes it well suited for imaging samples such as biological tissue, small animals, and industrial materials.

The GANYMEDE SD-OCT engine is housed in a 420 mm x 320 mm x 149 mm (16.54' x 12.6' x 5.86') unit. It contains a 930 nm Superluminescent Diode Light Source and a Linear Array-Based Spectrometer. It also includes all associated drive electronics and controllers.


Hand-Held Probe and Stand

All Thorlabs OCT systems include a hand-held probe and stand, as shown here. The probe provides X-Y scanning for three-dimensional data acquisition. A camera integrated in the probe provides live video imaging during OCT data acquisition. The probe easily slips onto the stand for imaging of small samples.
The probe stand consists of a post-mounted focus block which is attached to a specially designed 12" x 14" aluminum breadboard using a Ø1.5" P14 Post.

Stand Features

  • Ideal for Vibration-Sensitive Studies such as Doppler OCT Imaging
  • 3/4" Thick Aluminum Breadboard Provides Increased Stability
  • Breadboard Base has Side Grips and Recessed Feet for Easy Lifting and Transportation of the Stand
  • Includes a Sample Stage with 1" X and Y Travel as well as Rotation
