It can be generally known as a flat-discipline concentrating mirror or linear lens. As opposed to traditional focusing lenses that focus the focal location on a single issue, the scanning lens disperses the laser beam to a number of details within the scanning space or workpiece, creating a uniform centered location from the laser beam in your entire marking aircraft.
Knoop hardness (HK) can be a measure of a material's mechanical hardness which is most commonly given for brittle elements. Knoop hardness is analyzed by urgent a pyramidal diamond-shaped indenter into a material sample and analyzing the resulting indentation in the fabric.
