Abstract: An arrangement for constructing a micro-optic bench that has rods (1) and mounts (2 or 3) for holding optical elements. The mounts are provided with perforations (4 or 5) through which the rods extend. The mounts can be locked into position on the rods by means of positive and non-positive snap-together fastenings in the vicinity of the perforations. The fastenings secure the mounts in place on the rods in such a way that they cannot be accidentally displaced. The arrangement or set can be assembled or disassembled without tools or supplementary parts.

Abstract: A set of connecting elements and mounting elements are provided with split openings and clamping means arranged selected distances apart and at selected orientations so that these elements may be attached to rods to form a multidimensional frame for mounting laboratory and experimenting equipment. Adjustable mounting devices are provided with three point supports centrally arranged on the mounting elements adjacent to apertures therein so that optical elements and other such devices may be supported on the mounting elements and so that the axes of such devices may be tipped or displaced as required for a particular situation.
