The probe consists of a photodiode with an appropriate filter and is provided with a diffuser for correct measurement according to the cosine law.

Measurement range: 1 mW/m² … 2000 W/m². Cable length 2 m.

The spectral response curve of the probe allows to measure the effective irradiance for blue light hazard (curve B (λ) according to the standards ACGIH / ICNIRP) in the spectral range from 380nm to 550nm. Optical radiations in this range can produce photochemical retinal injury. Another field of application is the monitoring of the blue light irradiance in the treatment of neonatal jaundice.

The probe is made of two sensors, the signals of the sensors are combined and weighted to obtain an accurate spectral response. The two probes are equipped with a diffuser for the correct measure according to the cosine law.

The probe provides the following data:

• Total Effective Irradiance (E_eff) – Measuring range: 0.01 W/m²…20 W/m².
• Effective Irradiance in the range UV-CB – Measuring range: 0.01 W/m²…20 W/m²
• Irradiance in the UVA spectrum – Measuring range: 0.1 W/m²…2000 W/m²

When used for the control of cosmetic tanning systems, with the LP471A-UVeff  it is easy to determine the exposure time for the first session (set to  100J/m² effective) and the total time per year (maximum dose limit established is 15kJ/m² per year). Alternatively you can calculate the dose received per session. You can also check the status of lamps aging by regularly measuring the solarium emission.

Supplied with SICRAM module and 2 m cable.

The probe works with the instruments: DO9847 (from rev. R.1), HD31, HD2302.0 (from rev. 01), HD2102.1 (from rev. 11) and HD2102.2 (from rev. 21).
