The Imaging Spheres systems are a unique approach to obtain angular data within seconds. The products are based on a novel optical configuration to allow simultaneous imaging of a target device or material from all directions on a hemisphere at once. This results in faster, more complete, and often more accurate measurement than can be achieved with traditional goniometric or conoscopic solutions. A ProMetric color or luminance camera is used to capture the image data, ensuring high accuracy in measurement. The Imaging Sphere can be configured for measurement of far field luminous intensity distributions for LEDs and other small light sources, display view angle performance, or the angular distribution of scattered light from surfaces (both BRDF and BTDF). The Imaging Sphere is ideal for both research and production applications for LEDs, FPDs, display components and material surface analysis.

 

Three base models of the imaging sphere are available, with options to configure the system for two or even all three measurement types:

 

IS - LI luminous intensity for LEDs and small sources

The IS-LI luminous intensity measurement system, provides comprehensive measurement of far-field luminous intensity, radiant intensity, CIE chromaticity coordinates, and correlated color temperature (CCT) distributions as a function of angle for LEDs and other small light sources. The IS-LI provides critical directionality information that is not available from integrating spheres.

 

IS - LI - TE portable system

The IS-LI-TE was especially designed for fast speed and small size applications such as in production line testing or income quality control.

 

IS - VA viewing angle for OLEDS and displays

The IS-VA view angle performance measurement system delivers high-speed, comprehensive measurements of color, luminance (brightness) and contrast as a function of view angle for flat panel displays and display components. The IS-VA compares extremely favorably with conoscopes and goniometric systems in terms of measurement speed and system cost.

 

IS - SA scatter & appearance

The IS-SA scatter and appearance measurement system integrates a focused light source, directly illuminating a material sample to measure scattered light. The IS-SA can accurately and rapidly characterize surface roughness, imperfections and diffusion properties for a wide range of reflective surfaces and transmissive films. The IS-SA generates detailed BRDFs and BTDFs with finer angular resolution and greater speed than goniometric systems. It also has far more flexibility in configuring measurements and the data can be exported into many ray tracing programs such as Light Tools or Trace Pro.
