The OCT Point Spread Function (PSF) Test Target from BioPixS is a precision-engineered cylindrical phantom designed to facilitate quantitative evaluation of OCT system resolution. Unlike layered phantoms, this target contains no stratified background structure, instead, it consists of FeO nanoparticles homogeneously suspended within a transparent polymer matrix.
With its clean geometry (10 mm diameter × 10 mm height) and uniform particle dispersion, this phantom allows researchers and device developers to accurately extract axial and lateral PSF profiles, making it ideal for benchmarking system optics, algorithm performance, and optical alignment.
Not only this phantom allows to test axial and spatial resolution of the OCT system, but our PSF phantoms also come with different concentrations and nanoparticle sizes to meet the testing requirements of a wide range of OCT systems.
