What are Stilb and Watt/sq. Cm/steradian

Stilb is a unit of luminance in the centimeter-gram-second (CGS) system of units. It measures the amount of light that emits or reflects from a surface per unit area in a specific direction. One stilb equals one candela per square centimeter. This unit is named after the Greek word 'stilbe,' meaning brightness, and is used primarily in photometry to quantify the intensity of light as perceived by the human eye. Although not commonly used in modern settings, stilb provides a historical insight into the development of photometric measurements.

Watt per square centimeter per steradian (W/sq.cm/sr) is a derived unit of radiant intensity in the International System of Units (SI). It measures the power emitted by a source per unit area per unit solid angle. This unit is crucial in fields like radiometry, where understanding the distribution of electromagnetic radiation is important. It helps quantify how much power is emitted in a specific direction per unit area, taking into account both the surface area and the solid angle over which the power is distributed. This measurement is key in applications such as calculating the efficiency of light sources and evaluating the intensity of radiation in various contexts.

History of Stilb and Watt/sq. Cm/steradian

Historically, the conversion from Stilb to Watt/sq. Cm/steradian at 555 Nm emerged from the need for a standardized method to measure light intensity in photometry and radiometry. Initially, stilb was widely used in the CGS system, but as technology advanced, the need for more precise and versatile units like watt/sq.cm/sr became apparent. This conversion is crucial in fields requiring precise light intensity measurements, such as optics and laser engineering. Consequently, the transition paved the way for improved accuracy in scientific research and practical applications.
