A device used to measure light levels or density in small areas, often used in photography and scientific research.
The scientist used a microphotometer to analyze the light transmission through the sample.
Microphotometer → It is formed from "micro-" (from Greek "mikros", meaning small) and "photometer" (from Greek "photos", meaning light, and "metron", meaning measure). The word refers to an instrument that measures small amounts of light.
Think of 'small' ('micro-') and 'measuring light' ('photometer') to remember that a microphotometer is a device that measures small quantities of light.
