Introduction

The RD Mathis point source loop filaments are designed for use as point sources for thermal vacuum evaporation systems. They are used for evaporating small pieces of metal wire which can be hanged in the loop or wrapped around the wire at the loop. The point source loop filaments are all made from tungsten wires in various thicknesses. Available as single strand sources and sources with 3 or 4 strands.
They can be used for upwards and sideways evaporation processes. Downwards evaporation is only advised when the substrate is not directly positioned under the evaporation point source filament. These point sources are suitable for:

• thin film processes that require small amounts of evaporant
• small amounts of expensive materials
• R & D and product development applications
• sample preparation applications
