T2 HANDHELD OCT SYSTEM
Coming soon, the Theia T2 Handheld OCT System is the world's first commercial* handheld swept source OCT system. The T2 system consists of a cart-mounted OCT engine, a long and flexible tether, and a lightweight handheld probe that accepts interchangeable lenses for imaging different regions of the eye (see available lens types below).

1
FASTER
Leveraging next-generation swept source technology, the T2’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 T2 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.
3
EASIER
The T2’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.
