👉 A microphotometer is a type of optical device that measures the size and shape of microscopic objects. It consists of a light source, typically a laser or a diode, and a photodetector that captures the light from the laser wave. The photodetector then converts the light into an electrical signal, which can be used to measure the size and shape of the object. Microphotometers are commonly used in medical imaging, where they can detect tiny structures such as cells or tissues
