Phototherapy is the use of light to cure ailments. Typical applications are in the treatment of skin diseases such as psoriasis and in the area of prenatal care, hyperbilirubinemia. As much of the treatments for skin diseases involves the use of UVA and UVB radiation, it is critical to correctly monitor the dosage. Over exposure to UV light can cause severe sunburn and cancer.

International Light carries a complete line of phototherapy radiometers for both research and diagnostic applications.

Just introduced! The IL74 Specialist Series Hyperbilirubinemia Monitor which can be used to directly measure the exposure level in the patient plane. See our datasheet (PDF).

The IL1402 and IL1702 UVA phototherapy radiometers include both the meter and specific detector configurations as well as the IL1403 and IL1703 UVB phototherapy radiometers.

The detectors, the SED(L)033/UVA/W(TD) and SED(L)240/UVB-1/W(TD) are also available separately. An optional detector, SED(L)/240/UVB/W(TD) is available for applications requiring better band discrimination. An XIR single wavelength calibration is available for TL series lamps at 311 nm, or SED005/TLD312/TD can be used.

The detector SEL005/TLS312/TD is also available, and is best suited for
TL-01 lamp measurement.

Specifications:

5.2mm² GaAsp Detector
TLS312 Filter
TD Diffuser
PIR(IPIR) Irradiance (W/cm²) Calibration.
Center wavelength: 312 nm.
IL1700 measurement range: 3.3 x 10^-8 to 3.3 x 10^-1.

The IL1704 and IL1404 Bilirubin Phototherapy radiometers are specifically designed to monitor lamp output in neonatal hyperbilirubinemia exposure chambers, with detectors designed to exactly match the photo-oxidation response of Bilirubin in the blood of Jaundice patients. These instruments are designed to measure in the 400nm to 500nm range. The IL1704 comes standard with the SED033/BR/W probe while the IL1404 comes standard with a compact SCL144 probe. Additional probes for wider spectral coverage are also available including the SED(L)033/TBLU/W with a wider spectral coverage.
