Lens-Free Microscopy Focuses on Commercialization Aug 8, 2019 — With advancements in image processing and sensors, lens-free microscopy is ready for a closer look by researchers, industry, and consumers. Compared to traditional benchtop microscopes, lens-free techniques can cost less, reduce instrument size, enlarge the field of view, and improve throughput. “The device [a lens-free microscope] is 10× smaller than a regular microscope. But the image, on the contrary, is 100× larger than any [other] microscope image,” said Cédric Allier, a project manager...
