Optics

What are you most excited about in the field of optics?

In this month's Technology Forum, Rob Morris with Ocean Optics, Robert E. Rachlis, consultant for optical systems and applications, and Howard Mark, with Mark Electronics discussed Optics/Lasers. Here is your chance to participate in their discussion.

This month's Technology Forum looks at the topic of Optics and Lasers and the trends and issues surrounding it. Joining us for this discussion are Rob Morris, with Ocean Optics, Inc., Lisa Tsufura, with Melles Griot, and relative newcomer to the LIBS community Daniel W. Merdes, with Penn State University.

What do you see in the future for Optics and Lasers?

This tutorial reviews the mathematical models for dealing with interelement effects in optical emission and X-ray fluorescence spectrochemical analysis. Line overlaps and matrix effect corrections are examined.

Wavelength Tech Forum: Optics & Lasers

Optics and Lasers Wavelength

The authors describe an in-situ cleaning verification technique that promises to be faster and more efficient than traditional methods, which use swab sampling followed by HPLC analysis. The technique is based upon FT-IR spectroscopy in the middle-infrared (mid-IR) range using reflection at a grazing angle.

The author provides a brief historical and technological review of different types of telescopes, and how they were developed and improved.

A fiber-optic, mid-IR spectroscopy probe combined with a grazing-angle reflectance sampling head can be used as a solvent-free, in situ method for validating cleanliness with substantial improvement in accuracy, compared with traditional methods.
