    Parabolic Cold Reflector
    Specifications
    Description If a light source is placed in the focal point of a parabolic reflector, the rays of light will be reflected paralled to one another, This will give a great concentration of light in a tight beam, rather than an effused spread. Moving the source toward the reflecotr will spread the light, while moving the source away from the reflector will cause the light rays to converge. These reflectors are coated with dichroic coating. Substrate is glass. Parabolic cold reflector is widely applied in various lighting devices.
