Thorlabs’ OCS1300SS Swept Source Optical Coherence Tomography System is ideal for imaging highly scattering samples such as small animals and biological tissue. The 1325 nm central wavelength and 6 mm coherence length of the swept laser source enables deep image penetration, up to 3 mm. The OCS1300SS includes a hand-held probe, probe mount, and computer with user software.

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.

Compared to Spectral Domain OCT technology, Swept Source Optical Coherence Tomography does not suffer from inherent sensitivity degradation at longer imaging depths. Therefore, these systems are the preferred choice where long imaging depths are desired.
