Monochromator Skin Light Tests in Cardiff

Health Inspectorate WalesThe Monochromator Skin Light Test has been developed in order to find out which particular wavelengths of ultra violet radiation you may be sensitive to.

If you develop severe sunburn or a rash caused or aggravated by the sun, the monochromator light test can establish which part of the solar spectrum is responsible.

The monochromator skin light test takes about one hour to complete. You will be required to return to the clinic the following day for about 15 – 30 minutes so we can read, assess and discuss the results. Just like sunburn the reaction of the skin to this test has a delayed response.

How does the monochromator light test work?

We will shine tiny circles (5mm in diameter) of ultra violet radiation onto the lower part of your back, about 24 in total. There are no significant side effects, although we do expect some of the tiny circles to go red. You may experience some mild itching of the test sites for a day or two after the test.
