Paraboloid mirror is a curved mirror that converts diverging light from a point of light source into parallel light. By making the paraboloid a curved surface, it is possible to retrieve parallel light more efficiently than a spherical concave mirror. An example use of paraboloid mirror is as a lamp reflector of a microscope.

◦It obtains high performance condensing by precision aspheric surface processing.
◦It can provide long-term stability because it has a protective scratch-resistant coating over aluminum.
◦It is easy to position the light source at the focusing point because there is a hole on the axis of the paraboloid.
◦By entering the thick parallel light, it allows the light to be collected at one point.

▶Different focal length, outer diameter and hole sizes not mentioned on-line or in our catalog are available as a custom product upon request.
▶Also available for ellipsoidal TCEA mirror for focusing light of the lamp at one point.

Attention

▶Light does not reach to the mirror surface when high directivity source is placed at focal point, so it is not available to get the effect of paraboloid mirror.
▶Light near the optical axis center is not reflected by the hole in the mirror, there is a case that intensity distribution of the parallel light becomes ring-shaped.
▶When focusing the light emitted from a parabolic mirror by a lens, it does not focused at one point by the influence of light incident on the lens directly from the lamp.
