The blue light spectrum is an essential part of the visible spectrum with wavelengths of about 400-480 nm. [1] Blue light is primarily generated by Light-Emitting Diodes (LED) lighting and digital screens, it has now become prevalent in the world around us. [2] LED lighting creates white light by combining blue light with other wavelengths ...
Wratten numbers are a labeling system for optical filters, usually for photographic use comprising a number sometimes followed by a letter. The number denotes the color of the filter, but is arbitrary and does not encode any information (the 80A–80D are blue, the next filters in numerical order, 81A–81EF, are orange); letters almost always ...
150 Em – 16,000 light-years – Diameter of the Small Magellanic Cloud, a dwarf galaxy orbiting the Milky Way; 200 Em – 21,500 light-years – Distance to OGLE-2005-BLG-390Lb, the most distant and the most Earth-like planet known; 240 Em – 25,000 light-years – Distance to the Canis Major Dwarf Galaxy

Blue light, a type of high-energy light, is part of the visible light spectrum. High-energy visible light (HEV light) is short-wave light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of purported negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related macular degeneration.
Shuji Nakamura (中村 修二, Nakamura Shūji, born May 22, 1954) is a Japanese-American electronic engineer and inventor of the blue LED, a major breakthrough in lighting technology. [5] Nakamura specializes in the field of semiconductor technology, and he is a professor of materials science at the College of Engineering of the University of ...

A perfect filter would remove particular wavelengths and leave plenty of light so a worker can see what he/she is working on. Wedge filter. A wedge filter is an optical filter so constructed that its thickness varies continuously or in steps in the shape of a wedge. The filter is used to modify the intensity distribution in a radiation beam. It ...
