Avotec’s Real Eye Nano Features PG&O’s Customized Optical Components

Precision Glass & Optics, announces the customization of two thin film optical components for a high-field magnetic resonance imaging (MRI) accessory developed by Avotec, Inc. The Real Eye Nano™ is an advanced visual presentation and eye-tracking system constructed entirely of glass and plastic, with a reduced size that makes it ideal for operation in confined MRI spaces.

Functional magnetic resonance imaging (fMRI) is a leading tool in the effort to understand how the human brain functions and a primary target of fMRI research is cognitive disorders associated with increasing age. Optical systems that provide both eye-tracking and visual stimulation are, and will continue to be, a key component in fMRI research.

Avotec Real Eye Nano for MRI Applications

PG&O developed the dielectric cold mirror and cylindrical prism mirror for the Real Eye Nano. The system allows the MRI patient to view a unique visual demonstration concurrently while the patient’s eyes are illuminated with near-infrared (980 nm) light supplied by an IR light-emitting diode (LED) / fused fiber cable / fiber bundle. PG&O contributed expertise in designing and applying the thin-film coating to the large dichroic mirror and in shaping the multi-element lens for this revolutionary fMRI system.

According to Dan Bukaty, Jr., president of PG&O, “It was a pleasure to work with Avotec on this interesting project. In manufacturing the dichroic mirror, we used our CMP cold mirror and shaped the optic using waterjet technology, which allows us to produce difficult shapes very affordably. The lens was created from a right angle prism that we coated per our customers specifications, then precisely shaped using our CNC machine.”
