APERTOMETER Meaning and Definition

1. An apertometer is a device used in the field of optics and photography to measure the diameter of the aperture of a lens or an optical instrument. The aperture refers to the opening through which light passes, and it plays a crucial role in determining the amount of light that reaches the image sensor or film.

   The apertometer consists of a calibrated scale with a specially designed central aperture and a magnifying system. To measure the aperture, the user aligns the lens or instrument with the central aperture of the apertometer. Through the magnifying system, the user can clearly observe the diameter of the aperture displayed on the calibrated scale.

   The measurements provided by an apertometer are essential in photography and optics because they directly affect the depth of field, exposure, and image quality. By accurately measuring the aperture diameter, photographers and professionals can control the amount of light entering the camera, thereby adjusting the exposure settings accordingly. Additionally, they can ensure sharpness and proper focus by optimizing the depth of field, which is determined by the aperture size.

   Overall, an apertometer is a valuable tool for photographers, optical engineers, and other professionals in the field of optics, enabling them to measure and assess the critical aspect of aperture diameter, facilitating the achievement of desired image quality, sharpness, and proper exposure.

2. An instrument for measuring the angular aperture of a microscope objective.

Etymology of APERTOMETER

The word "apertometer" does not have a well-established etymology as it is a relatively uncommon term. It appears to be a combination of two distinct words: "aperture" and "meter". Here is the etymology of each component:

1. Aperture: The word "aperture" comes from the Latin "apertura", which means "an opening" or "a hole". It entered English around the 15th century, originally referring to an opening, such as a hole or gap. In the context of photography or optics, "aperture" specifically refers to the opening of a camera lens that controls the amount of light entering.

2. Meter: The word "meter" derives from the Greek word "metron", meaning "measure". It entered English in the early 18th century and is typically used as a suffix denoting an instrument or device used for measurement.
