Spectral domain optical coherence tomography (SD-OCT) system is designed for low coherence non-invasive interferometric cross-sectional imaging of biological tissues. It can be used for medical diagnosis, biomedical imaging, and subsurface material inspection. Our modular system design allows users to configure the systems to meet their different or changing reserach needs.
Applications
Tomography imaging:
posterior segment of eye
anterior segment of eye
skin abnormality
assess skin burn scars
many other tissues or samples
multilayer film inspection
multilayer film thickness measurement
3D subsurface structural inspection
OCT Panel

Advantages of our SD-OCT systems
Modular design allows researchers to configure the scanner mounting and external optics to meet their changing imaging needs.
We offer help on software reconfiguration and packaging reconfiguration that could not be done with many other commercially available SD-OCT systems.
