Fiber Optics |
-
- Dolan-Jenner's
standard line includes over 300 different types of
fiber optic light guides. The two standard
constructions are straight ("B" type) and
dual branch ("E" type). Many tip
configurations are available for both ends, which
are listed in our Fiber Optic Selection Guide.
Some of the other
options available in choosing a standard fiber optic
cable are:
- PVC sheathing
- High-temperature
stainless steel sheathing
- Quartz fibers
- Economy-Grade
fibers
- Plastic fibers
If a standard product
does not fit the requirements of your application, a
modified standard or custom cable may be the answer.
Look in the Custom Fiber Optic section for more
information.

| Ringlights |
-
- Dolan-Jenner fiber
optic ringlights provide 360 degrees of on-axis,
shadow free illumination. Ringlights are especially
effective in reducing specular reflections, or
glare, on an object. To further reduce glare, a
polarizer/analyzer is available for some models.
Our ringlights can be
mounted onto most camera lenses and microscope
objectives, using the proper mounting adapter. All
of the available models can be mated with our Fiber-LiteŽ
quartz halogen illuminators to produce intense
light, with very little heat.
Ringlights are a
popular choice for applications requiring even and
diffuse illumination from all sides. Look in our
Illumination Solutions catalog for dimensions and
other specifications.

| Backlights |
-
- Backlighting is a
machine vision lighting method which provides a high
contrast silhouette of a part segment. Made with
durable glass fiber optics, Dolan-Jenner backlights
can be used with any of our Fiber-LiteŽ
quartz-halogen illuminators.
Backlights can be
used with color filters, placed on the input end, to
improve the contrast of color tinted parts. The use
of glass fiber optics, as opposed to plastic,
enables the backlights to be used with high
intensity illuminators. High intensity lamps tend to
damage plastic fiber optics. Patented and
other patents pending..

| Line
Lights |
-
- The Line Light design
allows the structuring of light from round light
source input to a line output configuration. The
area of illumination coverage is defined by the
length of the fiber optic line, the 68 degree light
output cone on both axis and the stand-off distance.
The output will be most uniform on the central axis
and equal to the length of the fiber optic line.
Thus, selection of the light should be equal or
slightly longer than the target. Decreasing the
stand-off distance will increase the level of
illumination.
Line Light
configurations with quartz-halogen sources are
efficient in distributing extremely high levels of
cold light and are easily used with Dolan-Jenner
strobe sources. An application evaluated with a
quartz-halogen source will provide the same results
when interfaced to a strobe source.
Single Line Light, QF
type, are usually interfaced with line scan camera
web applications. If higher light levels are desired
to increase the application through-put or stand-off
distance a rod lens can be selected. A rod lens can
provide a stripe in excess of 7,000 foot-candles at
12 inches, over seven times brighter than the non-lensed
set-up.
Dual Light Lines, QDF
type, can be utilized for two line scan camera use
or with area array cameras to evenly illuminate
relative flat area targets or to match up with the
geometry of long targets such as cans, bottles,
containers, rods, etc. Alignment relative to target
geometry and angles of incidence are important
parameters in obtaining an optimum image.
The dual light line
fiber optics are randomized at the input end to
increase the uniformity at both output ends.
Positioning dual light lines bilateral at 45 degree
angles to the target allows for balancing the
illumination over an area. This illumination
balancing compensates for losses caused by the
outside rays from each line light assembly traveling
a longer distance. Thus, on a flat target surface
the illuminance from both outputs is summed and
provides balanced levels of area illumination.

| Custom
Fiber Optics |
-
- Our extensive standard
product line will fit a vast array of applications,
and are quickly and easily obtainable. However, if
your application requires a special design, we will
be happy to work with you on a custom product to
suit your needs.
The following
parameters should be considered when designing a
custom fiber optic cable:
- Fiber type
- Fiber bundle
diameter
- Sheathing material
- Special end tip
configurations
- Overall length of
cable
Using standard parts
(tips, sheathing, etc.) from our catalog in your
custom design will save on cost and lead times, but
we also have the resources available to manufacture
to your specific requirements. If a line-to-circle
configuration is required, look in our catalog for a
list of existing flare molds, to save on tooling
charges.
Dolan-Jenner can
assure competitive prices and quick deliveries on
your custom cable, whether you are interested in one
prototype, or several thousand units.

| Quartz
Fiber Optics |
-
- Because many
applications require special transmission
characteristics from our fiber optic cables, Dolan-Jenner
has four different types of quartz fiber available.
Quartz fiber is generally used to transmit light
from the infrared and ultraviolet regions of the
spectrum. Quartz fibers also have a smaller
numerical aperture than our standard glass.
Our IUV and UV grades
of plastic-clad quartz transmit to 220 nm, and our
IR grade transmits up to 2700 nm wavelength light.
Our quartz-on-quartz fiber can be used in
environments up to 2000 degrees F, is practically
free of secondary fluorescence at 254 nm, and
exhibits no discoloration under X-ray conditions.
For more information,
look in our Fiber Optic Selection Guide for
specifications and available standard products using
quartz fibers.
