Abstract:
    An ultra violet radiation detector comprises a slice of silica (10) having an entrance slit (18) from which radiation diverges to a curved reflective face (20, 22) which reflects it to a planar diffraction grating (28) as a convergent beam. The grating focuses a required spectral order on an array of UV detectors (24). Usually the first order spectrum is focused. The detector may be hand held.
