Optical table cleaning devices and methods of cleaning optical tables

A cleaning device for an optical table, the cleaning device comprising:

• a manifold defining a fluid passage and a vacuum passage;
• a top plate;
• a base plate;
• a plurality of vacuum assemblies, the plurality of vacuum assemblies including a vacuum outlet extending through at least a portion of the top plate and coupled to the vacuum passage of the manifold;
• a plurality of nozzle assemblies fluidly coupled to the fluid passage of the manifold and to the plurality of vacuum assemblies and each of the plurality of nozzle assemblies including a nozzle configured to engage at least one hole of a plurality of holes formed in the optical table;
• and
• a gear assembly mechanically coupled to the plurality of nozzle assemblies, such that the gear assembly is configured to rotate the plurality of nozzle assemblies.

A method of cleaning at least one hole formed in an optical table, the method comprising:

• aligning a cleaning device having a nozzle assembly and a vacuum assembly with the optical table, such that a nozzle of the nozzle assembly is aligned with the at least one hole;
• lowering the cleaning device onto the optical table such that the nozzle of the nozzle assembly is inserted within the at least one hole;
• activating the nozzle assembly such that a cleaning fluid is supplied to the at least one hole;
• and
• activating the vacuum assembly such that a vacuum is generated within the at least one hole;
• wherein the nozzle assembly and the vacuum assembly are activated simultaneously.
