  3. Photometry (optics) - Wikipedia

    en.wikipedia.org/wiki/Photometry_(optics)

    Luminous intensity (photometric) and radiant intensity (radiometric) In photometric quantities every wavelength is weighted according to how sensitive the human eye is to it, while radiometric quantities use unweighted absolute power. For example, the eye responds much more strongly to green light than to red, so a green source will have ...

  4. Radiometry - Wikipedia

    en.wikipedia.org/wiki/Radiometry

    Comparison of photometric and radiometric quantities. Radiometry is a set of techniques for measuring electromagnetic radiation, including visible light.Radiometric techniques in optics characterize the distribution of the radiation's power in space, as opposed to photometric techniques, which characterize the light's interaction with the human eye.

    en.wikipedia.org/wiki/List_of_Lighting_Design...

    This is a list of lighting design software for use in analyzing photometrics, BIM (Building Information Modeling), and 3D modeling. The software is typically used by importing the structural design via CAD files. Then lighting elements are inserted. And finally, the lighting objects are associated with a photometry via IES files.

  6. List of free geology software - Wikipedia

    en.wikipedia.org/wiki/List_of_free_geology_software

    This is a list of free and open-source software for geological data handling and interpretation. The list is split into broad categories, depending on the intended use of the software and its scope of functionality. Notice that 'free and open-source' requires that the source code is available and users are given a free software license.

  7. Spectral power distribution - Wikipedia

    en.wikipedia.org/wiki/Spectral_power_distribution

    Mathematically, for the spectral power distribution of a radiant exitance or irradiance one may write: =where M(λ) is the spectral irradiance (or exitance) of the light (SI units: W/m 2 = kg·m −1 ·s −3); Φ is the radiant flux of the source (SI unit: watt, W); A is the area over which the radiant flux is integrated (SI unit: square meter, m 2); and λ is the wavelength (SI unit: meter, m).

  9. Spectroradiometer - Wikipedia

    en.wikipedia.org/wiki/Spectroradiometer

    The field of spectroradiometry concerns itself with the measurement of absolute radiometric quantities in narrow wavelength intervals. [1] It is useful to sample the spectrum with narrow bandwidth and wavelength increments because many sources have line structures [2] Most often in spectroradiometry, spectral irradiance is the desired measurement.
