A UV LED provides the UV source in this test rig. Because of its construction
there is no radiation hazard and students can test the UV absorbing properties
of various materials such as lenses from sunglasses, various coloured glasses,
reflective film etc. as well as the effectiveness of sunscreen creams. UV
detection is by means of the UV beads and intensity is estimated from the
times taken for the colour changes to occur so approximate values only are
obtained. For more quantitative measurements, the UV Photo Detector (XOP 995
100) can be used. The unit requires a normal 12V DC power supply. Dimensions:
100 x 80 x 80mm overall ¥ Investigate UV absorption by sun creams and lenses
from sunglasses ¥ Ideal for use with the UV Photo Detector (XOP 955 100)
