Abstract
The invention relates to a polygon mirror which consists of defined cemented mirror segments placed at an angle on the cladding surface of a substrate each having a cement surface and an active surface. The polygon mirror is characterized by the fact that the substrate (4) is shaped in the form of a regular cylinder, whereby at least one external annulus (19) of a top layer (13) of a substrate (4) is positioned at a defined angle to the cladding layer (18), the mirror segments (3) having a radius of (r<-2) on their inner side forming the cement layer (19), said radius being greater than the radius (r<-1) of the cladding layer (18) by the width of a cement gap, the active layer (10) of each mirror segment (3) in the direction of the circumferential diameter being divided into a first sublayer, which is an interference layer (17), and into a second sublayer, which is a mirror surface (16), and the interference layer (17) of each mirror segment (3) being aligned at an identical angle for all mirror segments (3) of the polygon mirror in relation to an alignment surface (11) on a side surface of the mirror segment (3). Furthermore, the relation relates to a device and a process for the production of the polygon mirror.
