Abstract: Coating a machined mold with a flowable, hardenable polymer coating produces an optically-smooth finish and maintains sharpness in upward-pointing features. These procedures produce molds for highly efficient plano-convex silicone-on-glass lens arrays in a fast and inexpensive manner in which an end-mill defines the shape of a lens, and the coating produces its smoothness. End-mill machining and coating lens-shaped features in plates that have movable pins produce molds with eject features disposed inside features that form templates for lens elements without significantly reducing optical performance. Additionally, machining and coating plates that have movable inserts produce molds for lens arrays with reduced volume and one or several rings in each lens element.

Abstract: A connection protector kit for use with an electrical stub connection assembly, the stub connection assembly including first and second conductors forming a connection and defining a crotch therebetween, includes an insert assembly. The insert assembly includes an insert member and a sealant pad mounted on the insert member. The insert assembly is adapted to fit within the crotch of the stub connection assembly. The kit may further-include a cap defining a cavity and an opening communicating with the cavity, wherein the cavity and the opening are adapted to receive the stub connection assembly and the insert assembly is adapted to fit within the crotch of the stub connection assembly when the stub connection assembly is mounted in the cavity.
