Pro-Lite Technology

In this white paper, Pro-Lite’s Robert Yeo explains how the integrating sphere came into existence, what it does, how it works, and how it is used to simplify what would otherwise be complex measurements in fields such as radiometry & photometry, in measuring the optical properties of materials and in the calibration and distortion correction of cameras and image sensors.

Hyperspectral sensors offer a number of advantages thanks to their ability to identify and quantify molecular absorption. Hyperspectral imaging is widely used in applications including food and agriculture, mineralogy, surveillance, astronomy, chemical imaging and many more. This white paper provides a glimpse of some new developments within hyperspectral imaging technology, highlighting what is a rapidly changing imaging landscape.

The science of measuring the amount, spectral and spatial distribution of light emitted by a source is generally poorly understood. Few university-level physics or engineering syllabuses review the principles of optical radiation measurement, let alone the practicalities. This is despite our interacting with light almost constantly, both in nature and in our work and leisure activities. This white paper reviews the fundamental principles of light metrology.

This white paper will review the theory of Shack-Hartmann wavefront sensing and explain how it can be used to simply and quickly assess the quality of optical systems.

This white paper will explain how the optical performance of displays is quantified, and the instruments commonly used in display photometry and colorimetry will be presented.
