-
Use the result for lighting analysis, calibration, or design purposes.
Key Features
-
Converts lumen/square centimeter values directly to candela steradian per square meter.
-
Facilitates comparison between small-scale and standard illumination units.
-
Supports applications in LED manufacturing, laboratory photometry, lighting design, and photography.
-
Browser-based and user-friendly interface for quick conversions.
Examples
-
0.5 lumen/square centimeter converts to 5000 candela steradian/sq. meter.
-
2 lumen/square centimeter converts to 20000 candela steradian/sq. meter.
Common Use Cases
-
Specifying output intensity of small high-power LEDs or LED dies in terms of brightness per area.
-
Determining illuminance on microscope slides or small sensors in laboratory photometry.
-
Calibrating light meters for precision photography and instrument calibration.
-
Designing and verifying lighting levels in offices, classrooms, roadways, and outdoor environments.
Tips & Best Practices
-
Ensure that the surface illumination is uniform when applying conversions for accurate results.
-
Consider environmental and geometric factors that might affect light measurements in practical use.
-
Use this conversion to translate small-scale photometric data into standard units compatible with lighting standards.
-
Apply the tool for precise calibration of displays and optical components requiring per-square-centimeter metrics.
Limitations
-
Conversion assumes uniform light distribution on surfaces without accounting for directionality or spectral qualities.
-
Environmental conditions and measurement setup can influence actual illumination beyond the unit conversion.
Frequently Asked Questions
-
What does lumen per square centimeter measure?
-
It measures illuminance as the luminous flux falling on each square centimeter of a surface, representing perceived brightness weighted by human eye sensitivity.
-
Is candela steradian per square meter equivalent to lux?
-
Yes, in photometric contexts, 1 candela steradian per square meter equals 1 lumen per square meter, which is the definition of lux.
-
Why convert lumen/square centimeter to candela steradian/sq. meter?
-
Converting helps translate precise, small-scale brightness data into commonly used SI illuminance units, improving compatibility with lighting design and calibration standards.
Key Terminology
-
Lumen/square centimeter
-
A photometric unit expressing luminous flux incident on one square centimeter of a surface, indicating brightness on small areas.
-
Candela steradian per square meter
-
A measure of illuminance numerically equal to lux, representing luminous flux per unit area in SI photometric units.
-
Illuminance
-
The luminous flux per unit area incident on a surface, usually measured in lux or equivalent units.
