Divine Devices: The Oldfield Microscope
This patented light microscope provides substantially improved image quality for a wide variety of specimens and also makes possible the observation of living samples that until now could be viewed only as dead specimens. Samples that usually are viewed after chemical staining frequently exhibit good detail without staining, and thus the real material rather than a distorted or contaminated sample is seen. The Oldfield Microscope uses one or more diffraction gratings to select specific frequencies from a white light source, enhancing both resolution and depth of focus. Many specimens so illuminated reveal substantially more detail than in conventional light microscopes.
