INVARIANT OPTO-MECHANICAL MOUNTS
InvarianTâ„¢ is M Squared's alignment-free opto-mechanical mount
technology. In contrast to traditional 'ball-and-spring' mounts,
which can drift with time and temperature and require operator
re-adjustment, InvarianT mounts are set at the M Squared factory
(using a proprietary manufacturing technique), and never
need realignment.

With Invariant, we are able to provide sealed, alignment-free
laser systems, leaving you to focus on results, not maintenance. An
additional benefit of InvarianT's stability is
that laser cavity designs can be folded easily to enable
highly miniaturised laser systems without fear of
alignment drift.
