A radiation detector, particularly suitable for use in computerized tomographic scanning systems, comprising a scintillator crystal having one window surface optically connected with a photodetector, preferably a semiconductor device, and having other surfaces diffused and tapered whereby the window surface is enabled to see all other surfaces so as to provide efficient passage of light photons from the crystal through the polished surface to the photodetector.
