AUTUM C. PYLANT, NEWS EDITOR, [email protected]A noninvasive laser that can “smell” could make diagnosing diseases easier. University of Adelaide researchers in Australia have created a laser that can differentiate between gases within a sample. The new device could be used for environmental monitoring and detecting industrial contamination, and also to diagnose disease by “smelling” a person’s breath. The device exploits a Nobel Prize-winning technology developed by U.S. and German scientists: an optical-frequency comb. The FC1500 frequency comb from Menlo Systems GmbH generates millions of different...Read full articleRelated content from Photonics MediaARTICLES3D-Printed Microlenses Correct Color Distortions in Small-Scale ImagesResearchers from the University of Stuttgart used a 3D-printing process called two-photon lithography to make highly precise lenses that are just a few micrometers in size and that reduce chromatic...Photonics Spectra August 2021 IssueRaman Spectroscopy and Machine Learning Team Up to Predict Immunotherapy Response in PatientsUsing Raman spectroscopy and machine learning, a team at Johns Hopkins University developed a noninvasive technique to assess how cancer patients will respond to immunotherapy.

These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookExcimer Optics: High Power Demands High Reliability: The excimer laser’s shift to commercial applications has created a demand for higher power levels and increased reliability from the laser itself, thus creating a greater demand for industrialized optics to control, redirect, reshape, and focus the intense UV radiation produced.The first high-reflectance mirror coatings for the UV and vacuum UV (VUV) were of the Al + MgF2 type produced in the late 1950s.
