The basic setup for a Foucault knife edge test consists of and illuminated pinhole size source, a knife edge, and the mirror or lens being tested. The pinhole source is placed at one center of curvature of a mirror (or say twice the focal distance of a lens), and the knife edge is placed near the image of the pinhole.

The knife edge is translated across the optical axis and the image of the light spot on a screen placed behind the lens or mirror is observed. As the knife edge is moved, the position of the light spot on the screen will change in a way that is related to the curvature of the lens or mirror. By measuring the position of the light spot on the screen as the knife edge is moved, it is possible to determine the curvature of the lens or mirror.

The microscope we most often see is called a light microscope. It uses a light to help us look at the tiny details of the thing we are investigating (our sample). We can use a light microscope to study cells, parasites and some bacteria. Look at the image of a microscope, and click on each part to find out how it helps us to investigate our sample.

Something is called ‘microscopic’ when it is too small to see with our eyes alone. Microscopes allow us to see these microscopic things, such as the tiny details of minerals, plants and animals. The study of microscopic things is called microscopy.

Magnification describes how much bigger an object is made to look through the microscope. If something has a 100x magnification, it looks 100 times bigger than its actual size.
