Paraboloidal Cold Reflectors | |

|
|
If
a light source is placed in the focal point of a parabolic reflector,
the rays of light will be reflected parallel 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 reflector 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 coatings which reflects visible light and transmitte IR light. Application: Parabolic
Cold Reflectors are widely applied in various lighting devices.
