Effect of Sandblasting on the Specular Reflection from Encoder Wheels
Yvette Mattley, Ocean Optics
Spectral reflectance measurements can compare objects of different colors and textures. In this application note, we showed the results of reflectivity of both metal and plastic encoder wheels before and after sandblasting. Sandblasting is often part of the process of preparing machined parts, and in this case may have been used to lessen the specular reflection of the metal and plastic materials.

Characterizing Electrical Contacts Using the Chemreveal™ LIBS Desktop Elemental Analyzer
TSI Inc.
Connectors and tracks on printed circuit boards supply power and pass signals between electronic components soldered to the board. While primarily made of copper, alloying agents and overcoating are frequently used to improve the manufacturability and durability of traces and contact points. This note reports on analysis metals contacts on an intact circuit board using LIBS. In a single analysis, we obtain information on noble and transition metals as well as beryllium in copper.

Measuring the Opacity of Plastic Tubing with Vis-NIR Spectroscopy
Yvette Mattley and Ruud Niesen, Ocean Optics
Plastic tubing is available in a variety of opacities ranging from clear to translucent. The transparency of plastic tubing is varied for reasons such as providing contrast for visual monitoring of fluid flow, decreasing exposure to ambient light, and making the tubing more distinct for machine vision technology. In this application note, visible-NIR transmission spectroscopy is used to assess the amount of frosting applied to plastic tubing to determine if the tubing meets the required opacity level.
