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.
APPLICATIONS
Phototherapy Lamp monitoring
Determining length of exposure
Clinical studies
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/nm. Treatment
power level guidelines are usually specified in this way.
Analog versions of this detector are available See PMA1123
