Wide-angle Enhanced Imaging Periscope (EIP) module with a large horizontal viewing window. The device features a dual-tone design: an olive-green top housing the viewport and a beige base unit with bolts and connection ports. A protective cover is mounted above the lens, likely for shielding the optics from environmental exposure.

Embedded Image Periscopes (EIP) custom module

All G&H EIP periscopes are designed to be modular and can be custom configured for both new vehicle requirements and as a direct replacement for current in-service solutions.
