The fiber optic connectivity receives input from the reflection off of the inner 3/4 in. diameter sphere surface. The IS1 is right for transportable color measurements and acts sort of a trigonometric function receptor for irradiance measurements. The fiber optic cable (20) includes a light-weight carrying center (28), a protective covering (30) and a buffer (32). The protective covering displacement instrumentality (10) has surfaces (60,62) which might be used for displacing the buffer (32) and protective covering (30) to reveal (34) the sunshine carrying center (28).
