NEW: irradiance detector by Gigahertz-Optik

Ultraviolet radiation is used in the treatment of certain skin diseases like Psoriasis and for photobiological studies like SPF testing. Measuring the source irradiance or energy is required for accurate dosimetry and safety purposes. Typical wavelength ranges of interest are UV-A320-400nm, UV-B280-320nm and UV-B311nm. The two cell XD-9501 detector includes filtered detectors for both the UV-A and UV-B spectral ranges and a cosine corrected field of view.

Traceable calibration

Calibration of the detector UV-A and UV-B (W/m²) responsivity is performed by the Gigahertz-Optik GmbH calibration laboratory for optical radiation measurements quantities. As with all light detectors supplied by Gigahertz-Optik calibration of absolute detector responsivity as well as detector individual measured relative spectral responsivity data is included.

The XD-45-HUV irradiance detector is designed for the evaluation of light exposure hazard values for artificial light sources. The three sensor design of this unique device covers the requirements for skin and eye risk assessment.

ICNIRP/ACGIH spectral responsivity The spectral effective function required for skin and eye risk evaluation is formed using two filtered sensors. This prevents the cross-talk and limited sensitivity between the UV-A, UV-B and UV-C spectral ranges inherent in a single filtered sensor solution. Using the two sensor method also produces a much better simulation of the ...

The XD-45-ERYC-4 irradiance detector is specially designed for the measurement of the Erythemal effective UV radiation in tanning equipment. In use with Gigahertz-Optik’s X14 optometer the mobile instrument enables health and safety executives to do on-site measurements at the tanning salon conforming to published safety standards.

Measurement of the UV-C Limit Value The relevant German UVSV (Verordnung zum Schutz vor schädlichen Wirkungen künstlicher ultravioletter Strahlung) specifies the limit values for Erythemal effective irradiance at 0.3 W/m² within the wavelength range from 250 to 400nm. From 200 to 280nm the irradiance should not exceed 0.003 W/m². Because of the isolate UV-C value the ...

The X97 (Xnine seven) meter in combination with one of Gigahertz-Optik’s irradiance detectors forms a compact hand-held radiometer for the measurement of irradiance in W/cm² and irradiance dose in J/cm² of polychromatic optical radiation within the ultra violet, visible or near infrared spectral range. It’s most common use is the periodical check and adjustment of the irradiance level of light sources.

Measurement of the irradiance of UV Radiation The UV-37 series detectors are designed for the measurement of low to mid intensity ultraviolet radiation. Gigahertz-Optik offers a selection of UV-37 detector for different wavelength ranges within the UV spectrum. All of them are supplied with a diffuse window for cosine corrected field-of-view. Measurement of the irrad...
