Abstract
A microdensitometer has been designed and built along modest lines for photographic research. It has a resolving power of about 850 lines/mm when the scanning aperture is 1 micron wide and 40 microns long. The response is linear down to 0.1% transmission for the same aperture. By narrowing the aperture, the resolving power can be increased to 2000 lines/mm. Visual readings can be taken on a self-contained meter or a recording can be made on chart paper with rectangular coordinates.
