    PRO8000, PRO8000-4 or PRO800. All modules must only be operated with duly shielded connection cables. Only with written consent from Thorlabs may changes to single components be carried out or components not supplied by Thorlabs be used. This precision device is only dispatchable if duly packed into the complete original packaging including the plastic form parts.
