Envelope grinding of micro-cylinder array lenses using

2021-3-1 In this paper, a novel method of envelope grinding using a near arc-profile wheel (EGNAW) without on-machine precision truing is proposed for the efficient fabrication of micro-cylinder array lenses. The analytical model of a tool path that can be used for CNC macro-programming is developed based on the normal-form algorithm.

An Introduction to the Optics Manufacturing Process

2008-10-31 Before the lens undergoes further grinding, the lens must be blocked, or mounted, to begin the process. Blocking involves mounting lenses onto a convex or concave surface (inverse of the tool being used) with pitch or wax. A lens can be blocked individually (Figure 3a), but more often, many lenses with the same radii are mounted on one surface
