It is actually often known as a flat-field focusing mirror or linear lens. As opposed to common focusing lenses that focus the focal location on one particular issue, the scanning lens disperses the laser beam to numerous points to the scanning spot or workpiece, developing a uniform targeted place with the laser beam in the whole marking aircraft.

Very good mechanical Homes:ZnSe has excellent mechanical Qualities, like higher hardness and toughness, making it appropriate for use in purposes wherever the windows could possibly be matter to higher worry or impression.
The selection detailed Here's for the transmission by way of a calcite substrate. Some items use optical cement or other supplies that may limit the transmission wavelength selection.
In isotropic materials, There exists a linear partnership concerning Poisson's ratio, Young's modulus, shear modulus, and bulk modulus. This causes it to be probable to compute any unknown moduli of specific products using only two recognized values.
where by Sij corresponds towards the elastic compliance constants and l1, l2 and l3 denote the direction cosines. Determine 6 shows the directional Younger’s modulus of both phases less than distinct hydrostatic pressures. The surface area contours with the Younger’s modulus of equally buildings turn into more anisotropic geometry with an ever-increasing stress, revealing that ZnSe in both equally B3 and B1 structures are inclined to become extra anisotropic as the hydrostatic strain get more info increases. The obtained result is in good arrangement with the response with the common elastic anisotropy index AU illustrated in Fig.
