Produktbeschreibung

general information:

The radiometric probe LP471-BLUE measures irradiance (W/m²) in the spectral band of blue light. The probe consists of a photodiode plus an appropriate filter and is provided with a diffusor for prober measurements in accordance with cosine law.

application areas:

The spectral response curve of the probe allows the measurement of the radiation that causes damages due to blue light (curve B(λ) according to the standards ACGIH / ICNIRP) in the spectral range from 380 nm to 550 nm. The radiation optics in this portion of the spectrum can produce photochemical damage to the retina. Another field of application is the monitoring of the probe irradiance of blue light used in the treatment of neonatal jaundice.
