An Apostilb is a unit of luminance, which measures the brightness of a surface as perceived by the human eye. It is primarily used in photometry to quantify the amount of light emitted, passed through, or reflected from a particular surface in a specific direction. The term originates from the Greek word 'apostellein', meaning 'to send forth'. One Apostilb is equivalent to 1/π candela per square meter, providing a practical measure for various lighting applications. This unit plays a crucial role in ensuring accurate lighting conditions in diverse fields, including photography, astronomy, and interior design.
Definition of Lumen/sq. Cm/steradianLumen per square centimeter per steradian (lm/cm²/sr) is a unit that quantifies the luminous intensity per unit area in a given direction. It combines three components: lumen, which measures the total quantity of visible light emitted; square centimeter, denoting the area over which the light is distributed; and steradian, representing the solid angle of light emission. This unit is crucial in fields requiring precise lighting measurements, such as optical engineering, display manufacturing, and architectural lighting design. It facilitates the assessment of light distribution, ensuring optimal visibility and energy efficiency in various applications.
