Etymology: "Orthoscopic" is built from two Greek elements that are each well documented. "Ortho-" comes from Ancient Greek "orthós", meaning straight, upright or correct, and "-scopic" comes from "skopós", an observer or watcher, related to the verb "skopéō", to look at or examine. Put together, the word literally describes something seen straight, with nothing bent or warped between the eye and the object. The second element is the more productive one in English. The Greek root "-scope" appears in instruments such as the microscope and telescope, and "-scopic" is the adjectival form that Latin-derived "-icus" supplied through Old French and Middle English. "Orthoscopic" is therefore a modern scientific coinage from classical parts, not a word the ancient Greeks themselves used, and it belongs to the optical vocabulary that grew up alongside those instruments.
