Near-Field (Imaging) Goniophotometers
Radiant Vision System's near-field (or imaging) goniophotometers takes advantage of an ProMetric CCD imaging photometer or colorimeter to record a 3D luminance model of a light source or display. From this, you can create rayset files used with optical design software for illumination design. Alternatively, the near-field rayset file can be traced to far-field luminous intensity values and standard photometric data files in LDT and IES formats created. Compared with a far-field goniophotometer, a near-field measurement requires less space. In addition, the NFMS near-field goniophotometer is potentially much more flexible, providing for up to 4 types of measurements in one instrument: near-field luminance distribution; far-field luminous intensity distribution; far-field luminous intensity via direct beam projection; and lit area luminance (or colour) uniformity measurements.
