Near-field goniophotometer RiGO801

The full determination of the data of luminaires and lamps becomes more and more important:

• Primary prerequisite of a correct illumination planning
• Simulation, development of luminaires and lamps
• Cataloging and presentation

The goniophotometer type RIGO801 utilizes a new image-resolving CCD measuring technique for determining ray data and luminous intensity distributions.

The correct determination of the luminous intensity distributions (Lid) of lamps and luminaires is performed far within their photometric limiting distance on the basis of image-resolved measurements of luminous intensity distributions. A CCD-camera is moved by a goniometer around the measuring object at rest on a spherical surface, with the radius of this sphere being fixed only by the field angle of the camera. Thus, the goniometer can also be installed in small laboratories.

Advantages

• Full description of the light emission by ray data
• Small dimensions of the set-up
• Measuring in normal position

Result data

• Luminous intensity distributions (LID)
• Ray data available in various formats (e.g. ASAP, SPEOS, LucidShape, LightTools, Zemax, SimuLux)
• Processing and archiving of the LVK data in a photometric database (LumCAT)
