Examples

“August 13th 1664, Samuel Pepys, Diary (London: Marshall Cavendish, 1988), 133. “Comes Mr. Reeve, with a microscope and scotoscope. […] The other [the scotoscope] he gives me, and is of value; and a curious curiosity it is to discover⟳ objects in a dark room with.””

“At present⟳ the scotoscope's field of view⟳ and viewing-range requirements are in conflict, and improvement of one results in a decreased capability in the other.”

“A scotoscope (night vision device) was the most versatile viewer examined and provided maximum viewing distance for all markers.”

“However, where the angular field can be below 40°, a scotoscope with a refractive objective becomes a very useful device even with this small cathode diameter.”
