【Technical Information】What is brightness? What is illuminance?

Introducing the difference between brightness represented by luminance and illuminance per unit area!

Both luminance and illuminance are measurement units that represent "brightness per unit area," but they define brightness on different surfaces. Luminance represents the "brightness per unit area" of a surface light source, such as a display, while illuminance represents the "brightness per unit area" of the surface illuminated by a light source. Our company offers products such as the color luminance meter "Hyperion," which uses XYZ interference filters, and the luminance and illuminance meter "Asteria," which can accommodate various measurement scenarios from inline measurement to field use. [Featured Products] ■ Color Luminance Meter "Hyperion" ■ Luminance and Illuminance Meter "Asteria" ■ Spectral Radiant Illuminance and Color Measurement System "OP-IRRAD-VIS" *For more details, please refer to the external link page or feel free to contact us.

Discussion on Far Infrared: Radiance and Irradiance of Far Infrared Radiation

Discussion on Far Infrared: Radiance and Irradiance of Far Infrared Radiation

Introducing the difference between far infrared radiation brightness and radiation illuminance!

AMK Co., Ltd. is a company that handles industrial far-infrared heaters, heating devices, and drying equipment. The energy radiated per unit area and per unit solid angle from the surface of far-infrared radiation (W), which indicates the brightness of the light source, is referred to as radiance (W/cm²/str). The radiance for each wavelength is expressed as spectral radiance according to Planck's law, and as the temperature increases, the radiance becomes higher and the peak wavelength shifts towards shorter wavelengths. By integrating the radiance at each wavelength derived from Planck's law, the radiance can be determined. Radiance = εσT^4 (where ε is emissivity, σ is 5060707×10^-12, and T is absolute temperature + temperature) The brightness is proportional to the fourth power of the temperature, which is known as the Stefan-Boltzmann law. This means that even a slight increase in the temperature of the heater will significantly enhance the heating effect. "Radiance" refers to the energy radiated from the surface of the heat source, while the energy received by the other side is called "irradiance," which is a completely different physical quantity. *For more details, please refer to the PDF document or feel free to contact us.*
