Honle launches broad band sensor for LED UV units

To enable the measurement of LED UV units, Dr. Hönle has developed a broad band sensor which can measure across the bandwidth of all LED wavelengths – from 365 to 405nm – with only one sensor.  

UV measurement assures production process security and for research and development, reliable and repeatable test results in the laboratory.   

The physical classification of the UV spectrum in the UVA region is from 400-320nm, UVB from 320-380nm and UVC from 280- 200nm; in most cases the spectral sensitivity of the sensor is adapted accordingly. The specific characteristics of a broad UV spectrum can therefore be analyzed in detail. However, LED irradiation units do not produce a broad UV spectrum, but emit narrow bandwidths at specific wavelengths. Therefore, any UV measurement of these bandwidths with conventional sensors is inaccurate.  

Dr. Hönle’s UV LED measuring sensor is attached to a standard UV meter which automatically identifies the LED sensor when connected. The measured value is displayed in W/cm² or mW/cm² with a maximum intensity of 20W/cm².
