The HD30 is an instrument for the spectral analysis of light in the visible and UV range. The instrument consists of a data logger and a series of measurement sensors. The HD30 calculates the photometric parameters. The spectral range depends on the sensor being used. The sensor probes are interchangeable and each one contains its own calibration data with the probe.
The sensor HD30.S1 analyzes the visible spectral range (380nm-780nm) and calculates the following photo-colorimetric quantities:Illuminance [lux], Correlated Color Temperature CCT [K], Trichromatic Coordi-nates [x,y] (CIE 1931) or [u’,v’](CIE1978), CRI (color rendering index, R1...R14, Ra) , PAR [μmolfot/sm2]
The sensor HD30.S2 analyzes the ultraviolet spectral band (220 nm-400 nm) and calculates the following radiometric quantities:UVA irradiance (W / m2), UVB irradiance (W / m2) and UVC irradiation (W / m2)
Data logger-indicator HD30.1 with the probe HD30.S1 (visible):
With traditional light meters you can just check the level of illuminance [lux] but not the quality of the illumination produced.Therefore it is necessary to accurately control the colorimetric characteristics of the sources installed in order to evaluate not only the quantity but also the quality.In the industrial environment, a high color rendering reduces the fatigue of visual fi eld and, in cosmetics, a high color rendering is needed to enhance the quality of the exhibits. Even more important is the control of the spectrum of the sources installed in the museum environment where the quality of lighting has the dual task of ensuring the optimum viewing of the exhibits (high CRI) and a low emission of blue-violet light that may degrade the materials of the exhibits.Some neonatal therapies are based on lamps that emit blue light, the appropriate level of radiation can be measured by using the HD30.1. In this case, the light emitted out of the useful spectral band not only decreases the effectiveness of the therapy but can be harmful
Data logger-indicator HD30.1 with the probe HD30.S2 (ultraviolet):The ultraviolet light is used in the most various industrial and civil sectors. Quite often it is not enough to know the total emission of the source, but it is crucial to know how this light is distributed in the spectrum. This is because many processes (sterilization, polymerization and others) are very sensitive to the wavelength of the incident light and not only to its intensity.In the medical fi eld, some diseases of the skin are treated with the use of UV lamps (UVB), also in this case not only the intensity of light that reaches the skin is important but also its wavelength.
