Customized Optical Components

Precision Glass & Optics (PG&O) (Santa Ana, CA) announced the customization of two thin-film optical components for a high-field magnetic resonance imaging (MRI) accessory developed by Avotec, Inc. (Stuart, FL). 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. 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.
