It is critical that the suppliers and customers have a consistent approach during the inspection process. These guidelines are intended to help ease communication between suppliers and customers for better products and business.Surface quality has become one of the most poorly understood specifications in the optics industry. A significant portion of the confusion stems from the two major competing (and largely...Photonics HandbookIntegrating Spheres: Collecting and Uniformly Distributing Light: The integrating sphere is a simple, yet often misunderstood, device for measuring optical radiation.An integrating sphere’s function is to spatially integrate radiant flux (light). However, before one can optimize a sphere design for a particular application, it is important to understand how...Photonics HandbookMeasuring Surface Roughness: The Benefits of Laser Confocal Microscopy: 3D imaging and ultrahigh resolution are ideal for the inspection of materials with defined surface finishes and textures.When evaluating the surface of a component, surface roughness can be assessed by eye or by rubbing it with a fingertip. Common expressions include “shiny,” “lusterless and...Photonics HandbookSpectroscopy: The Tools of the Trade: Understanding the whys and wherefores of a technology goes a long way toward solving your problem. Putting that knowledge to work requires an understanding of the tools of the trade and how to use them.All optical spectrometry techniques rely on the measurement of radiant power.
