Abstract
Изобретение относитс к оптике и может быть испольэозано в установках, предназначенных дл освещени или обработки различного рода изделий пучками сконцентрированного лазерного излучени , Цель изобретени - повышение равномерности распределени интенсивности в фокусируемом пр моугольнике. Устройство выполнено в виде фазового оптического элемента 1 - отражающей зонной пластинки с микрорельефом 2. Приведено соотношение дл определени высоты микрорельефа зон пластинки, обеспечивающее повышение равномерности распределени интенсивности в фокусируемом пр моугольнике. 2 ил. (ЛThe invention relates to optics and can be used in installations intended to illuminate or process various kinds of products with concentrated laser beams. The purpose of the invention is to increase the uniformity of the intensity distribution in a focused rectangle. The device is made in the form of a phase optical element 1 — a reflective zone plate with microrelief 2. A correlation is given for determining the height of the microrelief of the plate zones, ensuring an increase in the uniformity of the intensity distribution in the focused rectangle. 2 Il. (L
