Refractor telescope vs reflector4/25/2023 On this theory, however, the reflector could too, since modern astronomical mirrors are coated with aluminum, not silver. If mirror-non-appearance of vampires is due to the interaction of evil with silver, a refractor using a prism could still see vampires. This uses the optical principle of total internal reflection. (Also there was a big problem in the original version of this comic).įrequently, however, the right-angle transition at the base of the refractor telescope is done with a prism (an "image erector"). There are other problems, though, with reflecting telescopes see details below. As Space Vampires (like earth vampires) are widely believed to be made up and thus unlikely to interest most stargazers, this complaint is superfluous, and the reflecting telescope effectively has no flaws in comparison to the refracting telescope. The unstated reason for this is that vampires, according to some cultures, cannot be seen in a mirror. However, the punchline invalidates these complaints with the (apparently major) flaw listed with the reflecting telescope: It can't see space vampires. It first looks like the comic is simply trying to show that refracting has many flaws, such as expense, size and visibility (see more details below). (A third type, the catadioptric system telescope, uses both mirrors and lenses. A refracting telescope produces an image with a series of lenses. This comic compares two major types of optical telescopes: The refracting telescope and the reflecting telescope. Title text: On the other hand, the refractor's limited light-gathering means it's unable to make out shadow people or the dark god Chernabog.
