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.

FASTER

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.

2

LIGHTER

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.

EASIER

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.
