Information about the UV-Index (UVI)
The UV index is an international standard measurement of how strong the ultraviolet (UV) radiation from the sun is at a particular place on a particular day. It is a scale primarily used in daily forecasts aimed at the general public. The UV-Index is calculated by integrating the sun’s UV spectrum multiplied with the Erythema action curve (fig. 1, black curve and fig. 2, formula 1). That integral is divided by 25 mW/m2 to generate a convenient index value, which becomes essentially a scale of 0 to 10. The Erythema action curve is a wavelength resolved measure of the sunburn danger. It is maximised at 297nm (UVB) and then strongly decreases towards UVA radiation. Literature: A. F. McKinlay and B. L. Diffey, “A reference action spectrum for ultraviolet induced erythema in human skin” CIE Journal, 6-1, 17-22 (1987)
About the sglux ERYCA sensors
The ERYCA is designed for accurate measurement of the UV-Index. ERYCA’s error is <3% only which is sufficiently small for scientific and high performance commercial applications. The ERYCA is available as:
ERYCA_custom (SG01D-E18) photodiode, 1,25nA/UVI (0,50mm2 SiC detector chip)
ERYCA_advanced (SG01L-E5) cosine corrected photodiode, 2nA/UVI (1,0mm2 SiC chip)
ERYCA_science (SG01XL-E5) cosine corrected photodiode, 8nA/UVI (4,0mm2 SiC chip)
TOCON_ERYCA pre-amplified cosine corrected hermetically sealed low noise sensor with 5-15V power supply and approx. 100mV/UVI voltage output (SiC detector chip)
