Hagner ScreenMaster

The Hagner ScreenMaster is a small, handy and very easy-to-use instrument for measurement of luminance as well as illuminance over a range of 0.1-200,000 cd/m² and lux, respectively. With both automatic zeroing and on/off switch, the only controls needed are a four-position range selection switch, a hold button for retaining the displayed value and a switch for selection between luminance and illuminance.
The ScreenMaster is provided with two detectors, which both are carefully filtered to give a spectral response close to that of the human eye, as defined in CIE standards.
The detector on the front side of the instrument is well cosine corrected and used for measurement of illuminance, for instance on computer screens and in working areas.
The detector on the underneath side of the instrument is built into a tube and is used for measurement of luminance. The opening of the tube (= 1 cm? gives a measuring angle of 36º (The measured area = the base of a cone with a 36º top angle.) This implies that the instrument is well suited for e.g. determination of luminaces and contrasts on computer screens, background luminances and luminances from negativ viewing tables. (To avoid reflectance of ambient light the detectortube can be pressed against the light emitting surface when measuring on screens and tables.) By means of this detector it is furthermore possible to caculate transmission factors and film density.
The Hagner ScreenMaster is of course also most suitable for general evaluations of lighting quality.
