JILIN CITY, China, Feb. 10, 2022 — Researchers from the State Key Laboratory of Applied Optics, Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP) of the Chinese Academy of Sciences (CAS) have proposed a broadband, polarization- and angle-insensitive metamaterial absorber (MA) that covers the longwave infrared (LWIR) band. The design supports radiative cooling applications, as well as infrared imaging and thermal detection. MAs that are based on subwavelength periodic patterns can achieve perfect absorption at any target wavelength, depending on the design of their geometric parameters. Because they are...Read full articleRelated content from Photonics MediaARTICLESPassive Radiative Cooler is Built Using Common Household ItemsUsing “Scotch tape” and aluminum foil, engineers at UCLA built a passive radiative cooler that lowers outdoor temperatures without electricity or refrigerants.

Therefore, it’s useful for almost anyone involved in the specification and purchase of optical components to have some familiarity with the typical performance characteristics, trade-offs and limitations of various coating types, as well as some knowledge of the capabilities of common thin-film production technologies. This article provides an objective overview of both these topics.What are thin-film coatings? The purpose of any optical thin-film coating is to modify the transmittance and reflectance properties of the substrate material to which they are applied. Most coatings...Photonics HandbookUltraviolet Reflectance Imaging: Applications: Ultraviolet imaging has long been thought to be difficult and awkward by many photographers because of the difficulties encountered when using photographic film in the UV band. Digital ultraviolet imaging is becoming increasingly affordable and lends itself to a number of interesting applications that have been largely overlooked, and digital sensors are available that span the UV spectrum from 200 to 400 nm.Reflected-ultraviolet imaging is a rather mysterious area of the imaging field. There is relatively little actual UV imagery to be found on the Internet or in the literature compared to near-infrared...Photonics HandbookWHITEPAPERSCharacterization of Dry Electrolyte Polishing ProcessThe preservation of the form is demonstrated by complementary form measurements using Ai Focus Variation technique.
