The radiometric probe LP 471-BLUE measures irradiance (W/m
2
) in spectral band of blue light.
The probe consists of a photodiode plus an appropriate fi lter and it is provided with diffuser
for proper measure in accordance with the cosine law. The spectral response curve of the
probe allows to measure the radiation effective for damages caused by blue light (curve B(λ)
according to the standards ACGIH / ICNIRP) in the spectral range from 380nm to 550nm. The
radiation optics in this portion of the spectrum can produce photochemical damage to the
retina. Another fi eld of application is the monitoring of the probe irradiance from blue light used
in the treatment of neonatal jaundice.
