Stilb is a unit of luminance in the centimeter-gram-second (CGS) system, representing the brightness of a surface emitting light equally in all directions. Defined as one candela per square centimeter, it measures how much luminous flux is emitted per unit area. Stilb is particularly useful in scientific fields where precise light intensity measurements are essential, such as astronomy, physics, and engineering. Though not commonly used in everyday applications, understanding stilb is crucial for professionals needing accurate light intensity calculations and for those working with advanced optical instruments.
Definition of Lumen/sq. Cm/steradianLumen per square centimeter per steradian, often abbreviated as lm/cm²/sr, is a unit that quantifies the intensity of light emitted from a surface in a specific direction. It represents the luminous flux per unit solid angle per unit projected area. This unit is crucial for applications requiring directional light measurements, such as in photometric studies and the design of optical devices. By providing a precise measure of light intensity, it helps in the analysis and optimization of illumination systems. Understanding this unit is essential for professionals working in fields like lighting design, optical engineering, and visual display technologies.
Stilb (sb) | Lumen/sq. Cm/steradian (lm/cm²/sr) |
---|---|
0.01 sb | 0.0001 lm/cm²/sr |
0.1 sb | 0.001 lm/cm²/sr |
0.5 sb | 0.005 lm/cm²/sr |
1 sb | 0.01 lm/cm²/sr |
2 sb | 0.02 lm/cm²/sr |
5 sb | 0.05 lm/cm²/sr |
10 sb | 0.1 lm/cm²/sr |
20 sb | 0.2 lm/cm²/sr |
50 sb | 0.5 lm/cm²/sr |
100 sb | 1 lm/cm²/sr |
1 sb = 0.01 lm/cm²/sr
1 lm/cm²/sr = 100 sb
Example 1:
convert 5 sb to lm/cm²/sr:
5 sb = 5 × 0.01 lm/cm²/sr = 0.05 lm/cm²/sr
Example 2:
convert 3.5 sb to lm/cm²/sr:
3.5 sb = 3.5 × 0.01 lm/cm²/sr = 0.035 lm/cm²/sr
The Stilb to Lumen/sq. Cm/steradian Converter traces its roots back to early photometric studies, where precise light measurements were crucial. Originally, stilb served as a unit of luminance in the CGS system, offering a means to quantify light intensity emitted from surfaces. As technology advanced, the need to measure light directionally led to the development of lumen per square centimeter per steradian (lm/cm²/sr). This converter bridges these historical units, facilitating accurate conversions that support modern optical and lighting applications.
