DigInfo - movie.diginfo.tv Kikoh Giken's MLXK semiconductor laser light source, is a product that achieves a more uniform level of line light in the center, brightness distribution on both sides, and energy distribution. The new laser achieves a brightness distribution of plus or minus 10% at the center of the line light and at both ends, and thereby solves the problems faced by conventional line laser light sources. The laser beam can support various lasers, focal lengths, and wide angles to accommodate user needs by adjusting and assembling several complex lenses. Laser Expo

Квантовый каскадный лазер представляет собой полупроводниковый лазер, излучающий в ближнем и дальнем инфракрасном диапазоне. В отличие от обычных полупроводниковых лазеров, которые излучают электромагнитные волны посредством рекомбинации электрон-дырочных пар, преодолевающих запрещенную зону полупроводника, излучение квантового каскадного лазера возникает при переходе электронов между слоями гетероструктуры полупроводника и состоит из двух типов лучей, причём вторичный луч обладает весьма необычными свойствами и не требует больших затрат энергии.Данный тип лазеров может быть использован для наблюдения за уровнем загрязнения атмосферы, в охранных системах, а также в медицине, из-за своих размеров порядка 3мм, они могут быть непосредственно введены в организм человека для качественного и количественного определения содержания в тканях человека сложных химических соединений.

DigInfo - movie.diginfo.tv Kikoh Giken's non Gaussian beam semiconductor laser light source features the advantages of semiconductor lasers for irradiation of a fixed surface area and can therefore be used as a spot light source. The line light source comes with enhanced brightness uniformity. The new light source uses a red laser and a blue-violet laser with a focal length of 100mm and is available with a spot diameter of 15mm, 25mm and 50mm. Kikoh Giken solved this issue by developing a uniform laser light source with a brightness distribution of plus or minus 20%. The new laser light source was also designed with consideration of alternative light from other sources and as a result, the image processing range was expanded. Laser Expo
