Compact recording of the appearance of surfaces and thin films
Abstract:
For improvement of optical surfaces and reflectivity enhancing films and for comparison with their appearance after use or testing, it is necessary to observe and record the nature of a surface or film with high resolution. Modifications of standard Twyman-Green and knife-edge testing methods are presented which meet this need. The appearance of flat surfaces of 40-mm diam can be preserved on a single photographic emulsion. Examples showing film defects due to reflectivity or phase changes with resolution of a few microns are presented.

Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
