SphereOptics GmbH

Our partner Westboro Photonics offers high resolution, high performance imaging colorimeters for several key applications:

Electronic Displays

• measurement of uniformity, contrast, mura, gamma, gamut and MTF of flat-panel displays

Automotive, Avionics Graphics and Lighting

• measurement of luminance and color distribution of backlit panel graphics and control elements
• Westboro offers a turnkey solution for light balancing of avionics panels

Keyboards

• automatic measurement, identification and pass/fail analysis for luminance and chromaticity of backlit glyphs and other lit elements

Beam Pattern Analysis

• luminous intensity distribution of lamps and LEDs

Westboro Photonics offers additional integrated spectroradiometers on all colorimeter platforms.

SphereOptics provides a large spectrum of ultra-lightweight reflectance targets.. The Zenith LiteTM targets are built from a 1 mm or 2 mm Zenith Polymer® diffuser attached to a 10-15mm thick aluminum honeycomb structured plate by special PTFE high performance glue. The laminating technique allows multiple reflectivities on one target with no visible seams (max. width 1040 mm). Targets can be made to any size and combination of white and grey scale reflectivities. The unique backing can be drilled for easy attachment to other mounting devices.
