Multifocal confocal microscopy 

We have developed a multifocal chromatic confocal system that offers high lateral resolution and a large imaging range. The system is based on a single lens made of zinc selenide (ZnSe) material. By leveraging the chromatic dispersion of ZnSe, images can be captured in multiple planes. The system enables tomographic imaging of biological tissues in 3D with cellular resolution. It has been demonstrated to successfully image iron oxide nanoparticle phantoms as well as corneal samples. The developed technology could find applications in biomedical and industrial imaging, such as the visualization of calcifications, the digestive tract, epithelial tissue, and field-effect transistors, among others.
