Overview

LuminousOptics engineers have years of experience in designing and manufacturing high value standard and customized luminance and radiance standards. Our Luminance/Radiance integrating sphere systems are microprocessor-controlled instruments with multi-detector monitoring that achieve the highest accuracy available from a sphere-based standard. All standard and custom instruments are calibrated to National Institute of Standards and Technology (NIST) platforms providing precise results when calibrating photometers, radiometers, electronic imaging devices and camera arrays.

Luminance/ Radiance Systems are available in sphere sizes ranging from 4-inches (10.16cm) to 75-inches (1.90 m) in diameter to accommodate various luminance and radiance output requirements. Click here for our product Luminance/Radiance Standards selection guide which will quickly help you select the appropriate system for your application.

For customized solutions, use our Luminance/Radiance System Worksheet to collect the appropriate information for your application and measurement requirements. Our experienced team of mechanical designers and optical engineers will work with you to develop a system that meets your needs in both performance and price.

Applications include:

  • Calibration of Photometers and Radiometers
  • Calibration for Spectral Radiance and Irradiance
  • Calibration and testing of Electronic Imaging Devices

Luminous Intensity, usually applied to point sources is the measure of flux per unit solid angle, this is reported in lumens/steradian which is equal to the candela (cd). This figure of merit is most commonly used to describe the "brightness" of LEDs. Radiant Intensity has units of Watts/steradian.
