Moving both laser and worktable enhances microlithography technique.Hank HoganIn the past, researchers wanting to perform lithographic microfabrication on a nonflat lens or other optical surface have been thrown a curve — literally. Standard lithographic technology cannot do the job. Investigators, therefore, were restricted largely to planar surfaces, which can be less than...Read full articleRelated content from Photonics MediaARTICLESIridescent Spiders Provide Inspiration for Optics DesignThe iridescent signal produced by miniature Australian peacock spiders during courtship displays could provide inspiration for the development of light-dispersive components that would be able to...Photonics Spectra March 2018 IssueMolecular Vibrations Imaged for First TimeScientists at the University of California, Irvine (UCI), focused light down to the size of an atom to produce the first images of a molecule’s normal modes of vibration.

Since nanopositioning is a discipline that has enabled swiftly evolving application arenas as diverse as materials science, genomics, photonics, defense, biophysics, and semiconductors, it’s unsurprising that its pace of innovation is nothing short of blistering in recent years.By its original definition, a nanopositioning device is a mechanism capable of repeatedly delivering motion in increments as small as one nanometer. Lately demands from industry and research have...Photonics HandbookOptical Delay Lines: Key to Time-Resolved Measurements: To obtain an accurate means of creating reliable delays in any time-resolved spectroscopy or dynamic experiment, several factors about the delay line stage must be considered to reduce or eliminate errors associated with linear stages.One of the most critical elements of any time-resolved spectroscopy and dynamics experiment is the optical delay line. A typical optical delay line consists of a retroreflector or folding mirrors on...Photonics HandbookPositioning System Performance: Understanding the Rules: To make the right decisions and to ensure satisfactory performance in a positioning system, it is necessary to first have a grasp of performance parameters and an understanding of their definitions.Abbe Error — Linear off-axis errors introduced by angular deviations coupled to a moment arm at the point of interest on stage mounted devices (θ in Figure 1).
