RADIOGRAPHIC EQUIPMENT – VIEWERS, DENSITOMETERS, METERSLuminance -The screen luminance required depends on the density of the radiographs. Thefollowing luminance levels are recommended for the perception of information at various levels. Theluminance (or brightness) of the illuminated radiograph shall be not less than:30 cd/m2 for film densities < 2.510 cd/m2 for film densities > 2.5and wherever possible, approximately 100 cd/m2 or higher. These minimum values require thefollowing screen luminance’s.Film DensityMinimum Screen Luminance cd/m21 3001.5 1,0002 3,0002.5 10,0003 10,0003.5 30,0004 100,0004.5 300,000Cat Number Film Viewers Price (£)Lumin S Executive High Intensity Viewer (Density 3.5) 395.00Lumin S 500 Film viewer (Density 3.0) 210.00Kowolux Model 3 Film viewer (Density 4.4) 1,265.00Spare Tube for Lumin S viewers 7.50Spare Bulb for Kowolux Model 3 viewer 68.20Cat Number Light Meters Price (£)MKV1 Combined UV/White Light Meter 648.75DSE100X Spectroline UV/White Light Meter 603.00J221 UV Light Meter 310.00Lumin SClick here to return to contents page vPage 23
