Optical coherence tomography (OCT) is a non-invasive imaging technique that uses light waves to create detailed, cross-sectional images of the retina, the layer of tissue at the back of the eye that contains the photoreceptors responsible for detecting light. It works by illuminating the retina with light and measuring the reflections and scattering of the light as it bounces back through the tissue. The information collected is used to construct detailed images of the retina, which can be used to diagnose and monitor a wide range of eye diseases, including age-related macular degeneration, diabetic retinopathy, and glaucoma.

The optical-grade materials include our highly reflective white, greyscale, color, and wavelength reference materials, and fluorescent pigment-doped materials.
