Conoscopic Lens Accessory Adds View Angle Capability to Your Imaging Colorimeter

The Westboro Photonics conoscopic lens accessory uses Fourier optics to enable luminance and chromaticity measurements of flat panel displays out to +/-80 degrees from normal (160 degrees full angle). The conoscopic lens accessory can be fitted to the WP6E, WP6ES and WP512 series of imaging colorimeters or imaging spectral colorimeters. Please note that this lens is distinct from the Westboro Photonics Conometer 80 which is a dedicated imaging photometer configured for display view angle measurements.

With the conoscopic lens attached, the calibrated colorimeter system provides accurate and reliable measurements of many parameters as a function of viewing angle including luminance, chromaticity, contrast, gamma and gamma inversion, and more.

AR/VR Display Testing

With an optional 2mm entrance pupil adapter, the conoscopic lens provides a 160° horizontal and 160° vertical measurement field of view of near-to-eye displays (NEDs).

Key Features

  • ± 80° (160° total) measurement field of view
  • 0.001 cd/m2 sensitivity
  • Faster than goniometric measurements
  • Spectroradiometer integration (optional)

Compatible Colorimeters

The conoscopic lens accessory is compatible with the following Westboro Photonics instruments:

  • WP690E/ES 9-megapixel imaging colorimeters
  • WP6120E/ES 12-megapixel imaging colorimeters
  • WP512 imaging spectral colorimeter

Please note that we also offer an imaging photometer that is dedicated to display view angle measurements – the Conometer 80.
