Microscopic Observation Various types of stains can be used on a routine basis, to qualitatively assess microscope slide Video camera attached to a microscope and transmitted to a computer are dependent on the computer software, the mean, minimum, and maximum diameter, length to width ratio. the circumference. the surface area. the volume. and the centroid. Particle imaging greatly reduces the time required but the cost of the software and equipment is often prohibitive for many small laboratoriesMicroscopic Observation Various types of stains can be used on a routine basis, to qualitatively assess microscope slide.
