OvaScope Egg Candlers Battery-powerded egg candler accommodates small up to duck/turkey-size eggs The light source is an LED which has the advantage of being very bright whilst remaining cool so prolonged observation of eggs (even small eggs) is not harmful to the embryos. The innovative EggScope allows the egg and embryo to be examined in more detail than has been possible before. Compared with handheld candlers, the clarity and visibility of the egg and its contents is also improved by completely blocking out ambient light and slightly magnifying the image, as well as allowing the viewer to rotate the egg smoothly as it is observed. Any webcam can be hooked up to the viewing piece making it ideal for classroom use.
