RMS 1200 – Determination of retroreflection values for all types of retroreflectors with precise color temperature control

The RMS 1200 from the Optronik line from Instrument Systems measures the back reflection of retroreflectors of all kinds in the automotive field and other retroreflecting materials. High-precision measurements are made in accordance with CIE Publication 54.2-2001 and reliably fulfil all current requirements, e.g. ECE R3, SAE J594, ISO-EN-DIN 20471 or DIN 67520.

The instrument is characterized by precise color temperature control of the projector light source to standard illuminant A. Only seconds after being switched on, the light source is stabilized and a color temperature of 2856 Kelvin is reached. As color temperature is measured and stabilized internally, the RMS 1200 retroreflectometer delivers reliable test results in accordance with CIE Publication 54.2-2001.

The RMS 1200 is controlled by the LightCon software of an AMS goniometer or special software for applications such as ISO 20471.

RMS 1200 – Product details:

  • Several model variants with freely selectable viewing angles of 0.1 to 2° (for a distance of 100 feet) with 0.001° resolution
  • Special measurement optics to avoid the effects of extraneous light
  • V (λ) alignment ≤ 2.0% in accordance with CIE Publication 54.2-2001
  • Display of color temperature, duty cycles and service life of the projector lamp
  • Can be combined with all AMS goniometers of the Optronik line

Product certification of retroreflectors with standard compliance

The RMS 1200 is used for product approval of automotive retroreflectors and stands in the light channel together with a CIE Type A goniometer of the AMS series. Measurements can thus be carried out from any angle required by the standard. The detector of the RMS 1200 ensures that the sample is always in focus. The automatic dark current compensation ensures that small measurement values are captured accurately and reproducibly.

The RMS 1200 is also suitable as a standalone measuring instrument or for special applications such as the measurement of retroreflecting foils and tapes for high visibility  clothing.
