A clamp for chromatography columns has a first seal with a first opening a movable seal with a second opening and a movable coupler. The movable coupler has first and second coupler seals with communicating third and fourth openings. The clamp is arranged for pressing a first chromatography column between the first seal and the first coupler seal and for pressing a second chromatography column between the movable seal and the second coupler seal, such that the first opening fluidly communicates with the second opening through the first chromatography column, the third and fourth openings and the second chromatography column.

A beam steering module comprised of a mirror stack array in close proximity to a collimator array controllably steers photons along two axis and in a direction substantially less than 90 degrees to the collimator orientation. Several configurations of the module are described using single and double axis mirror rotation and relay optics. Optical telecommunications switches are shown using modules coupled to each other along flat and curved surfaces, with and without use of fold mirror and enabling a plurality of configuration options including photodetector optical power monitoring schemes that require no external power taps.
