Abstract:
We present a system based on digital holography suitable for the investigation of microscopic objects. To increase the resolution of the system a deep (193 nm) UV laser source has been used. A method for compensating aberrations due to the non-perfect optical elements used for the recording has been developed. The system allows the investigation of reflecting and transmitting samples.

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...
