Anti-reflective coatings reflect ultraviolet radiation.
Anti-reflective (AR) coatings provide numerous visual benefits to spectacle wearers. However, coating designers and manufacturers seem to have placed little or no emphasis on reflectance of wavelengths outside the visible spectrum. Ultraviolet (UV) radiation from sources behind the wearer can reflect from the back lens surface toward the wearer's eye. Various clear lens materials, with and with...
متن کاملUV-LED Curing Efficiency of Wood Coatings
Ultraviolet light emitting diodes (UV-LEDs) have attracted great interest in recent years. They can be used to polymerize coatings, such as those used for prefinished wood flooring. In this project, two lamps were compared for their suitability to be used on a wood flooring finishing line: a UV-microwave and a UV-LED lamp. Low heat emission was found for the UV-LED lamp compared to the UV-micro...
متن کاملCoatings for Ultraviolet Lithography
Research into an optical thin film coating that enhances the current design of lithographic excimer laser gratings operating at 193 and 157 nm has been performed. The goal of such research is to improve durability and reflective efficiency. Possible coating materials include the fluorides, magnesium fluoride, barium fluoride, lanthanum fluoride and calcium fluoride. Each fluoride material was d...
متن کاملEvaluation of solar ultraviolet radiation in Zanjan city using the ultraviolet index
Background and Objective: Monitoring the amount of ultraviolet radiation from sunlight can provide a basis for assessing people's exposure, raise public awareness and warn people against this radiation. Measuring the sun's ultraviolet index over a working period is an accurate choice to achieve this goal. Materials and Methods: In this study, the amount of solar UV index in one of the outdoor ...
متن کاملThe Bystander Effect of Ultraviolet Radiation and Mediators
A bystander effect is biological changes in non-irradiated cells by transmitted signals from irradiated bystander cells, which causes the radiation toxic effects on the adjacent non-irradiated tissues. This phenomenon occurs by agents such as ionizing radiation, ultraviolet radiation (UVR) and chemotherapy. The bystander effect includes biological processes such as damage to DNA, cell death, ch...
