BioPixS’ OCT Pyramid test targets are advanced calibration phantoms designed to support multidimensional performance assessment of Optical Coherence Tomography (OCT) systems. These targets feature pyramid-shaped structures with high-precision step patterns (40, 80, or 120 μm pitch and 50 μm step height), embedded into an optically relevant polymer substrate.
Available in positive or negative relief configurations, these pyramid targets are ideal for testing axial resolution, field uniformity, distortion correction, focus depth, and field-of-view consistency. Their well-characterized geometry and optical properties (μa = 0.19 cm⁻¹, μs’ = 8 cm⁻¹) provide an essential platform for validating OCT performance across hardware setups and software pipelines.
