MICROPRISM Meaning and
Definition
-
A microprism refers to a small, transparent optical element commonly found in viewfinders or focusing screens of cameras. It consists of a series of tiny, closely spaced pyramidal structures or prisms that are etched or molded onto a glass surface. The purpose of a microprism is to assist with accurate manual focusing in photography.
When light enters a camera's viewfinder and passes through the microprism, it hits these finely patterned prisms, causing the light rays to bend and refract. This alteration creates a noticeable disturbance or shimmering effect on the viewfinder image when the subject is not in focus. As the photographer slightly adjusts the focus of the lens, the viewfinder image sharpens, and the shimmering effect diminishes.
In practical terms, the microprism acts as a visual aid to determine when an image is correctly focused. It is particularly useful in situations where autofocus may struggle, such as low-light conditions or subjects with low contrast. By observing the behavior of the microprism, photographers can ensure desired elements within the frame are in proper focus.
Microprisms have been a common feature in many film cameras, and some modern digital cameras also incorporate them, although electronic viewfinders and autofocus systems have largely replaced their usage. Nevertheless, microprisms remain popular among photographers who prefer manual focusing or utilize vintage equipment.

Etymology of MICROPRISM
The word "microprism" is composed of two parts:
1. "Micro-": The prefix "micro-" comes from the Greek word "mikrós", meaning "small" or "tiny". It is commonly used in English to indicate smallness or microscopic scale.
2. "Prism": The term "prism" originates from the Greek word "prísma", which means "something sawed off" or "a form with an oblique angle". In optics, a prism is a transparent object with a triangular cross-section that refracts light, causing it to disperse and form a spectrum. Prisms are widely used in optics and photography to manipulate and separate light.
Therefore, the etymology of "microprism" can be understood as a combination of "micro-" indicating something small and "prism" relating to the optical properties of the object.
