T1 INVESTIGATIONAL SYSTEM
Available now for research customers, the Theia T1 Investigational System is the world's first commercial handheld swept source OCT system. The T1 system consists of a cart-mounted OCT engine, a long and flexible tether, and a lightweight handheld probe that accepts various interchangeable lenses for imaging different regions of the eye (see available lens types below).
Please note, the T1 system has not been cleared by the FDA and is available only for investigational use with appropriate IRB and/or IACUC approvals.
Theia is currently developing a clinical device, based on the T1 system, that will be available once appropriate regulatory clearances have been obtained. Please contact us for more details.
Example images from the T1 device:
peripheral scan (A), macular scan (B), en face retina view (C) and pupil camera view (D).
Leveraging next-generation swept source technology, the T1’s 300kHz A-scan rate provides an order of magnitude reduction in image acquisition time, simplifying image capture and enabling dense volume sampling, even with squirming subjects.
At under 350 grams (12 oz), the T1 imaging probe weighs in at less than a quarter of the weight of competitive devices, eliminating hand fatigue and providing an extra factor of safety for imaging delicate subjects.
The T1’s handheld probe features a revolutionary ergonomic design that simplifies image alignment. Infrared illumination eliminates the need for a bright, uncomfortable flash, minimizing patient discomfort and aversion.

45 degrees* FOV
10µm lateral resolution
Optional integrated pupil camera (not compatible with interchangeable lens system)
* Theia reports retinal FOVs using using a standard “visual angle” definition per ISO 10940. This 45-degree FOV is roughly equivalent to a 70-degree FOV using “internal angle” definitions.
STANDARD RETINA LENS
> 110 degree* FOV
24µm lateral resolution
Requires corneal contact and coupling fluid (artificial tears)
Reusable contact tip (disposable option coming soon)
* Theia reports retinal FOVs using using a standard “visual angle” definition per ISO 10940. This 110-degree FOV is roughly equivalent to a 150-degree FOV using “internal angle” definitions.
