The image displays a lineup of candidates for Optica's 2027 offices. On the left, it features two candidates for Vice President: Luiz Davidovich and Peter J. Delfyett. On the right, four candidates are shown for Director at Large for 2027–2029: Sterling Backus, Eric Mottay, Alfred B. U'Ren, and Frédérique Vanholsbeeck.

A visually engaging infographic titled "Measuring Time" with a historical timeline about the evolution of time measurement. It includes several color-coded text boxes with dates and descriptions, small images of timekeeping devices, and significant places like Stonehenge. Key milestones feature Ptolemy, the French Revolution calendar, and developments by NIST. There's an image of a colorful atomic clock setup and a photo of Stonehenge at the bottom.

An example of the integrated acousto-optic devices being developed at Sandia, such as the eight-inch wafer shown here.
Overview of the method for quantifying elements in plankton using soft X-ray spectro-tychography. By extracting transmittance changes from tychographic images acquired before and after the elemental absorption edge, the elemental distribution in plankton is quantified with high resolution and sensitivity.

A graphic titled "Congress is considering harmful budget cuts to science and innovation programs." It warns that these cuts may weaken the economy, undermine national security, and limit opportunity. Proposed cuts are listed with percentages: National Science Foundation -55%, National Institute of Standards and Technology -23%, Department of Energy, Office of Science -13.5%, NASA -23%, and Department of Defense, Basic & Applied Research -13.5%. A note says, "Contact your Rep," urging investment in innovation. The image includes the Optica logo.
White light passing through a multi-layer coated beam-splitter cube produces prism-like rainbows across its faces. Internal reflections, coating dispersion and local scattering/stress create the galaxy-like halo at the cube’s center.

The sensor. It is a small, gray metallic surface and is shown pressed against a person's fingertip.
Researchers showed that optical spring tracking could help enhance the signal clarity of gravitational-wave detectors. First author Scott M. Aronson is shown with the optical setup.
Two attendees at the Siegman International School on Lasers are engaged in discussion in front of a poster. One is actively pointing to sections of the poster presentation while the other holds papers. They are standing in a hallway filled with natural light.
