Photometer Assembly

A free standing tower that supports a precision rotating mirror system. A separate tower supports a rotatable photometer head frame for photometering of all types of luminaires. Headframe is configured with mounting plates both upward as well as the standard downward direction to allow tests on luminaires such as uplighters and bollards. Resolution of both axes is better than 0.001°.

Photocell

A Si-photovoltaic thermally stabilised photocell with high accuracy V-lambda correction using the full filter method. Colour response accuracy (F'1), including spectral reflectance of the mirror, better than 1% and comes complete with spectral response certificate. For accurate measurements the photocell has been selected for its low noise, high speed and exceptionally low drift performance.

Integrated Instrumentation

Measurement of lamp and ballast electrical and thermal characteristics go hand in hand with distribution photometry. All instruments used are of the finest quality available and are completely computer controlled.

Software

All software supplied with the R80 system is fully Windows based and professional reports can be produced within minutes of completion of test.
