MSC15-Bili Blue light phototherapy irradiance meter for all lamp types


The MSC15-Bili is a compact spectral light meter for measuring irradiation intensity of blue light phototherapy systems irrespective of the lamp type or manufacturer. The meter conveniently measures the average and integrated irradiance in accordance with IEC 60601-2-50 and AAP Guidance. Each meter is supplied with a traceable calibration certificate from the ISO-17025 accredited Gigahertz-Optik laboratory.


The diverse range of available treatment lamps, which includes LEDs, various fluorescent tube types, tungsten halogen and metal halide lamps, produce widely differing spectral outputs. As there is no accepted action spectra for blue light phototherapy, manufacturers have tended to offer proprietary radiometers that are matched to their specific light source only. Significant errors can occur if used with other lamp types.


The MSC15-Bili spectral light meter provides a universal solution as it measures the actual spectral irradiance produced by the lamp and provides display modes in accordance with the latest standards and guidance. It directly displays total irradiance for bilirubin, Ebi (mW/cm2) in accordance with IEC 60601-2-50:2009+A1:2016 as well as average spectral irradiance (µW/cm2/nm) in accordance with the latest American Academy of Pediatrics, AAP, recommendations. Full spectral data is also available which enables the emulation of any proprietary wavelength band specified by a lamp manufacturer.


The meter provides individual display screens for AAP 2004 Guidance 430 nm – 490 nm and AAP 2011 Guidance 460 nm – 490 nm (μW/cm2/nm), and IEC 60601-2-50 Ebi, 400 nm – 550 nm (mW/cm2). Additionally, the meter measures spectral irradiance 360 nm – 830 nm providing lux, CCT and x,y chromaticity values. The AAP spectral irradiance range is better than: 0.01 – 250 µW/cm2/nm. The user can configure the meter to display only the required display screens. A color touch screen display provides intuitive handheld operation. The battery, designed for a full working day, can be charged with common USB chargers. The MSC15-Bili can also be operated via its USB interface with the included software.
