The primary concerns with CMOS technology are the rather low quality, noisy images that are obtained with respect to similar CCD devices. These are due primarily to process variations that produce a slightly different response in each pixel, which appears in the image as snow. Another problem is that the total amount of chip area that is sensitive to light is less in CMOS devices, thus making them less sensitive to light. These problems will be overcome as process technology advances and it is very possible that CMOS devices will eclipse the CCD as the technology of choice in the very near future. Short Takes The quality of a photomicrograph, either digital or recorded on film, is dependent upon the quality of the microscopy.
Film is a stern judge of how good the microscopy has been prior to capturing the image.
It is essential that the microscope be configured using K hler illumination, and that the field and condenser diaphragms are adjusted correctly and the condenser height is optimized. When properly adjusted, the microscope will yield images that have even illumination over the entire field of view and display the best compromise of contrast and resolution.
