Double convex axicons stand for optical components with a convex conical surface in combination with a convex spherical surface.
Optical axicons are optical components with a conical surface on one side and plan or spherical surface on the other side. They are made of optically transparent or filter materials with polished opposite sides, ground edges and chamfers. An axicon made up of conical and flat surface produces a line image along the axis from a point light source. On the other hand, an axicon made up of conical and spherical surfaces focus parallel beam into a ring on a given distance. The conical surface can be concave or convex depending of the axicon angle. Different coatings can be applied on the polished sides of axicons. The convex conical surface can be used as a mirror axicon.
Axicons are used to transform laser beams into infinite focus beams or to focus collimated beam into a ring. The later can be used for laser material processing.CONTACT US
