A UV sensor design which virtually eliminates solarization effects on optical components and photodetector and is effective for both broad area and collimated light sources. The sensor design reduces the number of photons striking a unit area of any of the materials in the light path sensitive to UV light to a level which does not produce appreciable solarization over very long periods of time. The UV sensor has as the first optical element in the viewing path a UV transmitting, extremely low solarization window. The back surface of this window is frosted to produce some diffusion of the UV rays. A small metal disc with a very small aperture is the next optical element and reduces the total amount of energy admitted to the optical measurement system. A second frosted UV transmitting, extremely low solarization window further diffuses the light beam passing through the aperture. The UV light from this second window travels toward to two UV filters and is further dispersed to produce low intensity level UV light which impinges on a silicon photodetector.

Composite materials that can be used to block ultraviolet radiation of a selected wavelength range are disclosed. The materials include dispersions of particles that exhibit optical resonance behavior, resulting in absorption cross-sections that substantially exceed the particles' geometric cross-sections. The particles are preferably manufactured as uniform nanosize encapsulated spheres, and dispersed evenly within a carrier material. Either the inner core or the outer shell of the particles comprises a conducting material exhibiting plasmon (Froehlich) resonance in a desired spectral band. The large absorption cross-sections ensure that a relatively small volume of particles will render the composite material fully opaque (or nearly so) to incident radiation of the resonance wavelength, blocking harmful radiation. The materials of the present invention can be used in manufacturing sunscreens, UV filters and blockers, ink, paints, lotions, gels, films, textiles, wound dressing and other solids having desired ultraviolet radiation-absorbing properties. The materials of the present invention can be used in systems consisting of reflecting substances such as paper or transparent support such as plastic or glass films. The particles can be further embedded in transparent plastic or glass beads to ensure a minimal distance between the particles.
