The PMA2123 is an accurate, stable detector designed to measure the output of phototherapy lamps used in neonatal wards to treat infant hyperbilirubenenima (jaundice). Blue light in the spectral range of 425-475 nm chemically alters bilirubin below the surface of the skin into products the infant can eliminate in urine.

The standard PMA2123 detector has a narrow spectral response from 425-475 nm, closely matching the action spectrum for bilirubin breakdown. The measurement will be accurate for the output of any lamp, in particular, blue fluorescent, daylight fluorescent and quartz halogen lamps commonly used in bili light units. The PMA2123 detector is calibrated to read in µW/cm².
