Web3M™ Specular Film DF2000MA is a polymeric film providing specular reflection with greater than 99% reflectivity of visible light. This metal free, non-corroding and nonconducting film is well-suited for daylighting applications. WebThis film is an ultra-high reflectivity, mirror-like, multilayer optical enhancement film that is commonly used as a highly efficient light guide or bulb cavity reflector. It is a non-metallic 100% polymer film with a reflectivity of 98.5% across the visible spectrum. continuous barrier withstand voltage

WebJul 18, 2012 · In this apparatus, the specular reflection from the tear surface is captured using a video camera, fed into a TV monitor, and recorded using a digital video recorder. Several studies have been performed to evaluate the tear film, especially that of dry eye, by non-invasive interferometry. WebThis device enables specular reflection oven the entire cornea through a cylindrical source of white fluorescent light onto the lipid layer. ... tear film lipid layer was examined using a ... WebJun 17, 2024 · Yes, specular reflection from polished gold is gold colored. Due to the interband transition in gold, green and blue light gets strongly absorbed, biasing the reflected spectrum toward yellow and red. This has nothing to do with diffuse scattering. continuous background checks
