Industrial laboratories have traditionally used 4” x 5” (100 x 125 mm) photomicrographs. Polaroid 4” x 5” prints have largely replaced glass plate and sheet film contact prints in industrial laboratories. High resolution 2000 by 3000 pixel imaging systems should be able to match the resolution of the 4” x 5” photomicrographs, typically 6 cycles per mm at a magnification of 500 times N.A., with a significantly larger field size which better utilizes modern, wide field optics. CCD cameras with 1024x 1280 pixel sensor arrays should be able to essentially match Polaroid 4” x 5“ photomicrograph prints in field size and resolution.
