Abstract
A parallax free sight has an optical element, preferably arranged at one end of an elongated light channel. A concave side thereof is parabolically shaped and provided with a partially reflecting layer, in the focal point of which is arranged a light emitting means. The element is moulded in one piece of a plastic material, preferably polycarbonate, and an opposite, convex side is elliptically or hyperbolically shaped, such that any light beam hitting it from the outside continues straight through it with minimal deviation.
