Use this tool for precise brightness evaluation in small-scale photometric applications
Limitations
-
Measurements on lumen/square centimeter involve much smaller scales, requiring careful instrument accuracy
-
Not suitable for all illumination ranges without proper calibration and equipment
Frequently Asked Questions
-
What does lumen per square meter measure?
-
It measures illuminance as the luminous flux incident uniformly on one square meter of a surface, equivalent to lux.
-
Why convert from lumen/square meter to lumen/square centimeter?
-
To evaluate light intensity over much smaller surface areas like LED dies or microscope slides for detailed brightness analysis.
-
Can this tool be used for photography lighting settings?
-
Yes, it helps measure and adjust exposure levels in photography and cinematography accurately.
Key Terminology
-
Lumen per square meter (lm/m^2)
-
The illuminance unit representing one lumen of luminous flux uniformly falling on one square meter of surface, equivalent to lux.
-
Lumen per square centimeter
-
A photometric unit measuring luminous flux incident on one square centimeter, used for small-scale brightness evaluation.
-
Illuminance
-
A measure of the amount of visible light illuminating a surface, weighted by the human eye’s photopic response.
