The R100 is a state-of-the-art fully computerised rotating mirror photometer. It contains inbuilt precision lasers and can accommodate luminaires up to 1600 mm in length (standard model) with a variable test distance of 8m to 30m. These features allow testing of virtually all luminaire and lamp types with a single machine. Sources of alignment error such as mirror tilt, test lamp/luminaire and photocell positions are negligible using the precision alignment system.

A free standing tower supporting a precision rotating mirror and pivoting headframe for photometry of both direct and indirect type luminaires. The headframe is positively locked in the up and down position by precision machined locating pins. The hinged mirror and its counterbalance rotate about a fixed shaft and are driven by a zero back-lash toothed belt combined with a harmonic geared dc servo motor. Resolution for both luminaire and mirror positions is 0.001°.
During setup of the test luminaire or lamp, all functions of the photometer are available via a dedicated hand controller. This includes alignment laser power, mirror and luminaire rotation and luminaire raising/lowering. The ease of operation yields excellent repeatability of laboratory results.
This is 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.
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.
All software supplied with the R100 system is fully Windows based and professional reports can be produced within minutes of completion of test.
