Large-Aperture Metalens Images Lunar Surface
Researchers at Penn State have developed a metalens that is large enough to be put into a telescope, and used the optic to image the moon's surface. The metalens, which the researchers used to create a metalens telecscope instrument, works in the near-infrared range with nearly diffraction-limited focal spot sizes and a high peak focusing efficiency of 80.84% at 1450 nm experimentally.

Method Achieves Nanoscopic Measure of Electron Dynamics in Semiconductor Materials
With the continued miniaturization of electronic and photonic devices, tools to examine the behavior of free electrons, simultaneously at the picosecond-time and nanometer-length scales, have become necessary. Now, A method developed by researchers at the University of California, Berkeley is poised to allow more effective measurement of these electrons, opening paths to better energy efficiency. The researchers developed what they described as a new type of optical nanoscopy to measure electron dynamics in semiconductors.

Understanding the Modulation Transfer Function and Beginning the Lens Selection Process
Tue, Mar 21, 2023 1:00 PM - 2:00 PM EDT
Stuart Singer of Schneider Optics, Inc. discusses how to understand the modulation transfer function (MTF) with respect to lens performance, while avoiding complex math such as fast Fourier transforms. The MTF is often the most important aspect of a lens because it shows how well a lens is able to reproduce the object within its view. Singer shares the steps that are needed to begin selecting a proper lens that meets specific imaging and system requirements. Finally, he details which lenses are appropriate for various imaging systems. Sponsored by Optikos Corporation and Navitar Inc.
