Thorlabs will acquire Columbia, S.C.-based Cirtemo LLC, including its two unique technologies, multivariate optical elements (MOEs) for spectroscopic chemical analysis and nanopatterning tools used to “3D print” photolithography masks using nanoparticles. Cirtemo’s MOEs are wide-band optical spectral filters capable of detecting complex chemical signatures using a simplified optical instrument, effectively replacing a dispersive spectrometer with a compact instrument that uses a single element detector. Although MOEs are fabricated using the same techniques as...Read full articleRelated content from Photonics MediaARTICLESPhotonics News: Week in Brief: 09/03/21MUNICH — TOPTICA Photonics’ TOPTICA Projects has successfully tested an experimental laser, jointly developed with the European Southern Observatory (ESO), MPB Communications (MPBC), and...Photonics.com 9/3/2021AmeriCOM Secures First College Partner for Precision Optics ConsortiumSussex County Community College (SCCC) in New Jersey is the first college to partner with the American Center for Optics Manufacturing (AmeriCOM), under AmeriCOM’s Department of Defense-funded,...Photonics Spectra November 2021 IssuePeople in the News: 06/09/21SAN JOSE, Calif. — Lumentum Holdings appointed Isaac Harris, corporate vice president of global supply chain operations for ZT Systems, to its board of directors as an independent member.
