Vintage Philips Marine Prism Viewer Optical Navigation Instrument

This Vintage Philips Marine Prism Viewer Optical Navigation Instrument redirects a line of sight on board ships. Crew used units like this to view a compass or instrument when direct viewing was blocked. Philips Telecommunication made these for marine and industrial use, and this example carries a “Made in Holland” marking.

The unit has a cast metal housing and a large optical lens assembly. In addition, the front gear rotates the internal lenses for controlled adjustment. The base includes mounting points so that you can secure it to a console or bulkhead. Because of its industrial design, it also fits well in offices, shops, or nautical interiors.
