Abstract: A collimating system utilizes a Rainbow.RTM. disk for holding and adjusting the position of the collimating lens. By applying a voltage to the two surfaces of the Rainbow.RTM. disk, the disk changes shape which causes the position of the collimating lens to be displaced. By adjusting the amount of voltage applied to the disk, the position of the collimating lens can be precisely adjusted to provide a substantially collimating light beam.

Abstract: A thermoelectric cooler subassembly in which all connections between a thermister and the thermoelectric cooler are attached to a cold side of the thermoelectric cooler and avoid contact with a hot side of the thermoelectric cooler which reduces the sensing of the ambient temperature, as well as the hot side of the thermoelectric cooler, by the thermistor thereby providing a more accurate temperature control.

Abstract: A cold welding system in which a dual sputtering device is carried on a rotatable arm and is rotated into a coating position between two stationary aligned substrates on a press and simultaneously coats both substrates and then is rotated out of the coating position so the coated substrates can be pressed together. A pair of shutters are pivotably connected to the rotatable arm and can be pivoted from a sputtered blocking position, where the shutters block sputtering in a direction towards the substrates, to a sputterer operating position where the shutters permit sputtering towards the substrates.
