Ray Generator (aka Trident Scanner) from Star Trek: The Original Series (Paramount TV, 1966-1969).

Prominent engineering tool seen in episodes "Metamorphosis", "The Doomsday Machine" and "The Ultimate Computer". Crafted of wood, turned aluminum, acrylic, plastic and brass components with internal wiring, the unique device is featured in the revered 1968 reference book The Making of Star Trek by Stephen E. Whitfield and Gene Roddenberry and is described as "...a (Spock built) ray generator and energy neutralizer." Measuring 16.5" x 10" x 3.5", the protrusion housing the translucent screen hinges upward to reveal a compartment with wiring where the light bulbs and battery were once installed (lights and battery are no longer present). A black button to the right of the screen once activated the lights. Exhibits age and production use including scattered scuffing and chips to gray paint finish, oxidation and warpage to brass screen on top edge of the unit from which the three scanner heads protrude. Electronics are no longer operational. Exhibited at the legendary Star Trek: The Exhibit at the Smithsonian National Air and Space Museum, Washington, D.C., February 1992 through January 1993. Comes with a COA from Heritage Auctions. From the Collection of Greg Jein.
