Abstract

Tom says, "I have just enough optical design knowledge to be dangerous, and I realized that if I had another 1.5-inch focal length lens I could construct a relay optical system within the diagonal." A relay lens takes the focused image coming out of a telescope and sends it onward to a second focal point or to another relay lens. He wanted the input lens to be as large as possible, so he looked for a second 1.5-inch-focal-length eye loupe lens that had a diameter around 1 inch. [Extracted from the article]
