Luminous Intensity / Radiant Intensity Probe / LPPHOT03 / LPPAR03

A probe designed for measuring illuminance and irradiance outdoors.

Measurement of illuminance (lux) in the near ultraviolet spectrum region VIS-NIR and the photon flux in the UVA, UVB, and PAR regions (400–700nm). ■LPPHOT03 Measurement of illuminance (lux), defined as the ratio of luminous flux (lumens) to unit area (m²). The spectral response curve of the photometric measurement probe approximates the response curve of the human eye known as the photopic standard sensitivity. ■LPPAR03 Measurement of the ratio of the number of photons incident on a surface per second to unit area (m²) in the spectral range of 400–700nm. This quantity is defined as PAR: Photosynthetically Active Radiation. ■LPUVA03 Measurement of radiative illuminance (W/m²), defined as the ratio of the radiative flux (W) incident on a surface to unit area (m²) in the UVA spectral range (315–400nm). With the adoption of a new photodiode, LPUVA03 is insensitive to visible and infrared light. ■LPUVB03BLAV Measurement of radiative illuminance (W/m²), defined as the ratio of the radiative flux (W) incident on a surface to unit area (m²) in the UVB spectral range (280–315nm). The spectral sensitivity is centered at 304nm with a bandwidth (FWHM) of 5nm.
