Technology for manufacturing diffraction gratings for spectrometry has not changed significantly in the past 40 years. But, according to Dr. Christoph M. Greiner of LightSmyth Technologies, that has changed thanks to deep-ultraviolet (DUV) reduction photolithography. In a feature article in the July issue of Photonics Tech Briefs, Dr. Greiner explains that for gratings, the DUV production optical stepper allows the design of more than 1,011 pixels on an individual basis. The ability to monolithically integrate multiple gratings on a single substrate using the DUV process makes it possible to integrate new functions into diffraction gratings.

Origin 8 Windows-based data analysis and graphing software from OriginLab Corp., Northampton, MA, has been named NTB's Product of the Month for July. The software operates around a revamped workbook space, which allows results of an analysis to be placed into a worksheet within the raw data's workbook. Parameter values, statistics, and related analysis graphs are available whenever looking at the original data. A new multi-sheet workbook feature keeps all related data, analyses, and graphs together. Sheets can be moved, added, inserted, or deleted. Workbooks in the new version also contain a new feature that allows users to embed graphs and images within cells to create a custom report. Click here for more info.

Techs of the Week

An electromagnetic actuator is a highly sensitive motion control device that employs more reliable and cleaner electromagnetic technologies to replace slower, less precise, larger, noisier, and environmentally unfriendly hydraulic omponents. This patented technology uses an armature in the form of a piston that moves on its own slide bearing rings. Fully sealed construction allows the actuators to operate underwater, in a vacuum, or in a hostile or sterile environment.
