The contractor will be responsible for restoring the microscope to operational status, which includes checking and repairing essential subsystems, performing mechanical and electronic alignments, and updating software controls.

Interested parties should contact Forest Crumpler or Donald Collie via email and ensure their company is registered in SAM.gov to respond to this sources sought notice, which is intended for market research purposes only and does not guarantee a contract award.
