In a traditional stereoscope base, the bulb is mounted below the stage plate. Because it shines directly upward into the eyes of the user, it obscures the view of the embryos. But the new Embryo-GLO Base eliminates that problem. Its variable halogen bulb is mounted in the rear of the base and shines toward a mirror below the stage plate, providing a clear view of the embryos. The user-adjustable tilting mirror allows for indirect lighting through embryos at various angles, illuminating the internal structures of the embryos. The double-sided mirror has a clear mirror on one side for bright focused light and a frosted mirror on the other side for diffused illumination. The halogen light assembly can also be mounted onto the adjustable upper illuminator bracket for incident lighting from above the embryos. The light control box features 4 brightness settings, allowing for brighter light when needed for higher magnifications.
