UV light is electromagnetic radiation with wavelengths shorter than visible light but longer than X-rays. UV is categorised into several wavelength ranges, with short-wavelength UV (UV-C) considered "germicidal UV". Wavelengths between about 200 nm and 300 nm are strongly absorbed by nucleic acids.
Halogen lamps with fused quartz envelopes are used as inexpensive UV light sources in the near UV range, from 400 to 300 nm, in some scientific instruments. Due to its black-body spectrum a filament light bulb is a very inefficient ultraviolet source, emitting only a fraction of a percent of its energy as UV, as explained by the black body ...
The Baofeng UV-5R [note 1] is a handheld radio transceiver manufactured by the Chinese manufacturer Baofeng. This model was the first dual band radio (VHF/UHF) to be successfully distributed by a Chinese brand. [citation needed] It is inexpensive and relatively simple to use (though tedious to program without computer software).
In August 2012, Hellman & Friedman agreed to sell Goodman Global to Japan's Daikin Industries Ltd. for $3.7 billion. In 2015, Daikin commenced construction of the state-of-the-art Daikin Texas Technology Park campus near Houston, Texas. This project, costing over $400 million, was the largest investment made in Daikin’s 90-year history.
In reflected UV photography the subject is illuminated directly by UV emitting lamps (radiation sources) or by strong sunlight. A UV transmitting filter is placed on the lens, which allows ultraviolet radiation to pass and which absorbs or blocks all light and infrared radiation. UV filters are made from special colored glass and may be coated ...
The DU was developed at National Technical Laboratories (later Beckman Instruments) under the direction of Arnold Orville Beckman, an American chemist and inventor. [13] [14] Beginning in 1940, National Technical Laboratories developed three in-house prototype models (A, B, C) and one limited distribution model (D) before moving to full commercial production with the DU in 1941.
