기능

• A curved mirror that converts divergent light from a point light source into parallel light.
• By making a curved surface a paraboloid, parallel light can be extracted more efficiently than a spherical concave mirror.
• Used as a lamp reflector in a microscope lamp house.
• High performance is obtained by precise aspherical machining.
• The aluminum coating has a protective coating that is resistant to scratches, so it can be used stably for a long time.
• The hole on the axis of the paraboloid makes it easy to place the lamp at the focal point.
• Thick parallel light can collect light at one point.
• Tempax (R) is a registered trademark of SCHOTT AG.
• An elliptical mirror (TCEA) is also available to focus the light from the lamp onto a single point.
• * When a light source with high directivity is placed at the focal point, light rays do not reach the mirror surface, so the effect of a parabolic mirror cannot be obtained.
• * Since the light near the center of the optical axis is not reflected by a hole in the mirror, the luminance distribution of parallel light may be a ring-shaped distribution.
• * When the light emitted from the parabolic mirror is focused by the lens, the light directly entering the lens from the lamp does not focus at one point.
