Application context
Hold every optic in a path at one consistent deck height so components can be swapped without realignment.
The structural link between an optic and the breadboard, where stiffness decides how well alignment survives.
Slide-and-clamp holders let a layout be rebuilt without unbolting the whole assembly.
Before you specify
Engineering context for choosing this class of component, with the tradeoffs worked through on real specifications.
Opto-mechanicsVibration, thermal drift and mechanical integration are one problem. Budget the motion at the sample, then specify the table, the isolation, the mounts and the beam height that budget asks for.
