Optical Rail Model Bc-4

In optical experiments, it is often necessary to translate components along an axis, e.g. when focusing a lens. The traditional solution is the optical bench consisting of a heavy cast-iron section (of Cat No. 1210 & 1211) of immense rigidity, carrying heavy, cast saddles. Such systems are still relevant for special single-axis work or (upto +2 level), but are relatively useless for multiple axis assemblies, especially when these axis intersect. and choice of different types of rail carriers.
