Thorlabs Extends OCT Offering to Include Spectral-Domain Polarization-Sensitive Device

Newton, NJ – December 5, 2018 – Thorlabs announced today that it has expanded its well-established Telesto™ OCT line to include two complete imaging systems that offer polarization-sensitive detection. With this new release, the TEL210PSC2 and TEL220PSC2 become the first commercially available Polarization-Sensitive Spectral-Domain OCT systems on the market, providing a new standard for highly reproducible and robust 2D and 3D imaging and analysis of polarizing samples.

As with Thorlabs’ previously released Telesto OCT technologies, these new systems are available in both long-range (TEL210PS) and general-purpose (TEL220PS – 5.5 µm axial resolution) variants. Each offers the same low roll-off and high sensitivity performance found in other members of the Telesto OCT family. In addition, the user can switch between different A-scan rate presets (ranging from 5 kHz to 76 kHz) to achieve an optimal balance between sensitivity and imaging speed. The unique polarization-sensitive detection and evaluation package allows for the analysis of parameters such as retardation, optic axis, and the degree of polarization uniformity.

“The new Polarization-Sensitive systems set a new standard for reproducible and ultra-stable OCT analysis of sample properties not currently available with standard OCT imaging,” said Matthias Pues, Project Manager for OCT applications at Thorlabs. “The OCT applications team is available to assist with sample test runs and would be pleased to discuss how our OCT systems can be adapted to meet your needs.”

Like all other Thorlabs OCT systems, the user can choose to purchase a complete, preconfigured system, which includes a scanner with dedicated imaging objective, scanner stand, and sample manipulation stage, or to opt for a user-configurable solution where the customer chooses from a large selection of modular components.

All Thorlabs OCT systems are shipped with a high-performance computer preinstalled with the new ThorImage®OCT 5.1 image acquisition software as well as a user-programmable Thorlabs OCT software development kit (SDK). To allow for custom data analysis, the user also has access to the raw data. For more information on Thorlabs' new Polarization-Sensitive OCT Imaging Systems, please visit
