Watt per Square Centimeter (at 555 nm)

W/cm² (at 555 nm)

Definition

The Watt per Square Centimeter (at 555 nm) is a unit of spectral irradiance that can be converted to illuminance at the peak sensitivity wavelength of the human eye. It represents the radiant power per unit area at 555 nm, weighted by the luminous efficacy of radiation.

History/Origin

Developed for converting between radiometric and photometric quantities at the peak sensitivity wavelength of human vision. It provides a bridge between physical light measurements and perceived brightness, using the luminous efficacy of 683 lumens per watt at 555 nm.

Current Use

Used in optical engineering, laser technology, and display characterization where the relationship between radiant power and perceived brightness is important. It allows for precise conversion from physical measurements to photometric quantities for monochromatic light sources.
