Optics irradiance
WebThis is the minimum irradiance or radiant exposure that may be incident upon the eye or skin without causing biological damage. The MPE varies by wavelength and duration of exposure and is documented in tables published in ANSI z136.1 standard. Think of the MPE as your laser safety speed limit. Nominal Ocular Hazard Distance (NOHD) WebThe radiance L is the irradiance per solid angle, or the optical power per unit area and solid angle. That solid angle refers to the directions from which the mentioned area receives light from the light source. The vertex of that solid angle is located at …

In radiometry, irradiance is the radiant flux received by a surface per unit area. The SI unit of irradiance is the watt per square metre (W⋅m ). The CGS unit erg per square centimetre per second (erg⋅cm ⋅s ) is often used in astronomy. Irradiance is often called intensity, but this term is avoided in radiometry where such … See more Irradiance Irradiance of a surface, denoted Ee ("e" for "energetic", to avoid confusion with photometric quantities), is defined as where See more The global irradiance on a horizontal surface on Earth consists of the direct irradiance Ee,dir and diffuse irradiance Ee,diff. On a tilted plane, there is another irradiance component, Ee,refl, which is the component that is reflected from the ground. The average … See more Irradiance of a surface is also, according to the definition of radiant flux, equal to the time-average of the component of the Poynting vector perpendicular to the surface: See more A point source of light produces spherical wavefronts. The irradiance in this case varies inversely with the square of the distance from the source. $${\displaystyle E={\frac {P}{A}}={\frac {P}{4\pi r^{2}}}.\,}$$ where See more • Albedo • Fluence • Illuminance • Insolation • Light diffusion • PI curve (photosynthesis-irradiance curve) See more
