Periscope design and manufacturing
A periscope is an optical instrument that conveys a panoramic view for surveillance, reconnaissance and navigation. Transmitting visual images through a long optical tube to the interior of a submarine and moving the line of sight in a vertical direction for safe positioning and navigation purposes.
Nedinsco covers the complete process from designing and manufacturing the entire periscope. From mechanical, high-end optical assemblies, to sub-assemblies for the entire periscope, with an emphasis on the eyepiece box, the tube and the drive mechanism (Motor Drive Unit).
For submarines and other military uses, the periscope consists essentially of a long tube with magnifying and relay lenses and prisms at both ends. Supported by an elevation prism for hemispheric images and auxiliary optics to display and overlay the camera images in the visual channel.
