Revolutionizing Optical Responses: Reflectance Measurements for Metasurface Wafer Technology

August 1, 2024

As we push the envelope to devise creative solutions to global problems, researchers have concentrated their efforts on the emerging field of metasurfaces. A metasurface is an engineered two-dimensional material designed to manipulate electromagnetic waves, such as light, in ways that are not possible with natural materials. These surfaces consist of arrays of subwavelength structures, […]

Assessing Protective Properties of Cosmetics with Directional Reflectance Measurements

July 21, 2017

[vc_row][vc_column width=”2/3″][vc_column_text]The damage caused by Ultraviolet (UV) radiation on human skin is well documented in medical research and cosmetic companies have developed products to protect the skin. The effects of Infrared radiation (IR) on skin is less clear but may include accelerated aging and increased severity of rosacea in people diagnosed with rosacea. The SOC […]

Measurement and analysis of optical surface properties for input to ShipIR

April 22, 2009

The application of advanced low observable treatments to ground vehicles has led to a requirement for a better understanding of effects of light scattering from surfaces. Measurements of the Bidirectional Reflectance Distribution Function (BRDF) fully describe the angular scattering properties of materials, and these may be used in signature simulations to quantitatively characterize the optical […]
