How the Shack-Hartmann wavefront sensing technique can be used to simply and quickly assess the quality of optical systems
How the Shack-Hartmann wavefront sensing technique can be used to simply and quickly assess the quality of optical systems
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.
Pro-Lite’s Robert Yeo reviews the science of integrating spheres and explains how they are used in reflectance spectroscopy.
In this white paper, Pro-Lite’s Robert Yeo explains the science of diffuse reflectance, presents Lambert’s cosine law and explains how a diffuse reflectance material appears equally bright from all angles of view. Commercially available diffuse reflectance materials and coatings are described from Labsphere and SphereOptics, while common applications for Lambertian materials are presented, in particular in the development of LIDAR and ADAS proximity sensors.
Gemma Church talks to Pro-Lite Technology about next-generation, cost-effective hyperspectral imaging technologies
In this white paper, Pro-Lite’s Dr Nick Barnett provides an update on the current and emerging technologies employed in commercially available multispectral and hyperspectral imagers. Spectral imaging is starting to become a mainstream imaging technology and is playing an increasing role in important topical issues of the day including recycling plastics, precision farming, food analysis and environmental monitoring.
Raman spectroscopy is powerful and versatile analytical tool that is applied in a vast array of applications from materials science to medical diagnostics. In this white paper, Pro-Lite explains how a new class of spectrometers developed by Wasatch Photonics results in compact Raman spectrometers far faster and more sensitive than typical compact spectrometers.
In photonics motion control applications, how do you combine speed with nanometric precision and unlimited travel? These seemingly conflicting requirements are uniquely addressed by ultrasonic, standing-wave, direct-drive piezoelectric motors. This technology provides unlimited linear or rotary motion of a ceramic tip that transfers drive to a target, operating in a manner similar to a DC servo motor but with much higher resolution, an order-of-magnitude higher speed and a wider dynamic range.
