Zusammenfassung:An apparatus and process for measuring light intensities includes the use of a probe. The probe is configured for monitoring a wavelength range from about 180 nanometers to about 270 nanometers (nm). The probe comprises a reflective and diffusive layer adapted for collecting light; a waveguide having one end in optical communication with the reflective and diffusive layer, wherein the waveguide has greater than about 50 percent transmission at wavelengths of about 180 nm to about 270 nm; a sensor probe in optical communication with the other end of the waveguide; and a filter intermediate to the waveguide and the sensor, wherein the filter is adapted to remove wavelengths greater than about 270 nm and has a percent transmission at wavelengths of about 180 nm to about 270 nm greater than about 50 percent.
