Scintillator discs coated with a very uniform layer of carefully selected P47 phosphor, highly recommended for routine use. They have a high signal output and a good working life. They should not normally be coated with aluminium, unless performing cathodoluminescence studies, as this reduces the efficiency by approximately 20%. Discs are available for all principal types of microscope, with special sizes available on request.
All discs are 1mm thick, unless otherwise specified.
