LINE ILLUMINATION / COLUMNAR ILLUMINATION /
CROSS-SECTION CONVERTERS
Increasingly, illumination is being demanded which provides a homogeneous and high intensity light line for image processing using line-scan cameras. In the field of fiber optics, this demand is met by cross-section converters or line illumination (also known as line lights) which achieve an optimal adjustment to the required illumination task.
Special applications employing fiber lines over: 10, 34, 36, 50, 70, 110, 125, 136, 260, 360, 500mm
Type of construktion:
+ Single- Cross- section converter /
fiber output angle
++ Single- Columnar illumination =
with lens system
+++ Dual- Cross -section converter / 2fiberline output angle
++++ Dual- Columnar illumination =
2fiberline output with lens system
+ ARC- Cross- section converter /
fiber output angle
++ ARC- Columnar illumination =
with lens system
e light input depends on the light source.
• The brightness and uniformity of the surface illumination requires a larger bundle diameter.
• The surface area of the fiber line resulting from
length x width determines the surface area of the round cross-section at the light input.
• The line width determines the attainable brightness.
• When selecting the line length,
the numeric aperture of the fiber being used
and the drop in brightness at the line ends must be kept in mind.
• The brightness drop at the line ends
is also influenced by the aperture of the receiver optics and the working distance.
• Cylindrical lenses on the fiber line focus the light one-dimensionally
and create narrow illumination bands (= line illumination).
• Working distances range from a few millimeters up to more than one meter.
• The light lines are available in acrylic, glass and quartz.
• We recommend the use of acrylic fibers for applications in the white light range.
