The port aligner range enables the distance and angular relationship between two flanges to be adjusted. The design consists of two parallel flanges, one of which remains fixed, whilst the second may be adjusted with respect to the first.

The fixed flange supports three equi-spaced threaded shafts. Alignment of the travelling flange is achieved by adjusting the floating mounts attached to each threaded shaft. The range can be mounted in any orientation and is bakeable to 250ºC.

A high quality, flexible, 316L edge welded bellows, spans the flanges to accommodate the required motion while ensuring an all-metal vacuum enclosure.

The range consists of three series mounted on CF38 (2-3/4” OD CF), CF64 (4-1/2” OD CF) and CF100 (6” OD CF) flanges. Each of which can be supplied with either tapped or clear holes. Each range provides +/-5mm axial adjustment, with a nominal amount of angular flexibility. Essentially, this is a simple device that once adjusted, provides a stable platform for instrument alignment.
