1 INTRODUCTION
The IQE-LIGHT-BIAS kit is used with Oriel’s IQE System when either white or colored biasing illumination
is needed. The light biasing source is adjusted manually.
This kit provides a light source with adjustable intensity levels and the means to install up to three
different colored filters when needed to bias a junction.
The kit includes an external quartz tungsten halogen light source, mounting flange, bifurcated fiber optic
cable and filter holder. A wide selection of filters are available from Oriel to meet a variety of testing
needs. These filters are purchased separately.
Prior to installation, read this instruction manual and all other documentation that came with this kit.
Check to ensure that all parts have been included with the kit. If there are any questions or concerns,
contact Oriel Instruments before installing this kit into the IQE system.
Included items:
66088 Light Source, with power cord and manual
90031273 Filter Assembly
77533 Bifurcated Fiber Bundle
77646 Focusing Beam Probe, with instruction sheet
Mounting and Light Adapters
77371-2-2900 Filter Wrench

2 INSTALLATION
Read all included documentation to understand the handling and care required for each of the system’s
components prior to beginning the installation.
1. Place the fiber light source in a convenient location where the power cord can reach the electrical
mains and the interface cord can reach the IQE system. This location must be less than 36
inches from the IQE System beam splitter assembly.
2. Attach the power cord to the fiber light source and complete all electrical connections.
3. Affix the filter assembly, minus the filter slide, to the front of the fiber light source by tightening
the thumb screw.
4. Install the mounting adapter onto the bottom output port of the beamsplitter on the IQE system.
When using with the IQE-200B system, it is necessary to first install the 71310 adjustable light
shield on the V-flange output port of the system before installing the mounting adapter. Tighten
the mounting adapter’s (3) set screws [A] to hold it in place. Refer to Figure 1.
5. The mounting adapter assembly includes two holders where the bifurcated fiber bundle’s legs are
installed. Each holder is secured to the mounting adapter with a set screw. Loosen the set
screws [B] so that the holders can swing freely. Refer to Figure 1.

6. Install the optional colored filters into the filter slide as shown in Figure 2 using the filter wrench
provided, or a spanner wrench, to tighten the retaining rings. Do not over tighten, as this will
damage the filters.
Note that the filter slide must have at least one of the filter locations left open (without a filter)
when white light biasing is required. Leave the retaining ring installed so that it does not get
misplaced.
FIGURE 2: GLASS FILTER INSTALLATION
7. Install the filter slide into the filter assembly, taking care that it is oriented exactly as shown in
Figure 3. The filter slide must be installed even if only white light biasing is desired, to prevent
light leakage.
8. Affix both 77646 beam probes onto the two legs of the 77533 fiber bundle. Refer to the
instructions provided with the beam probes. Ensure that the set screws on the beam probe
bodies are backed out far enough so as not to interfere with the fiber insertion and possibly cause
damage to the end face.
9. Install the common end of the fiber bundle into the filter slide and tighten the retaining screws,
after ensuring that the screws on the filter holder are backed out far enough so as not to interfere
with the fiber insertion and possibly cause damage to the end face.
10. Install each leg with its beam probe into the mounting adapter holders. Tighten the set screws [C]
as shown in Figure 1 to secure the fiber.

11. Ensure that the beam probes are not aimed at the eyes of any person. Then turn on the fiber
light source and move the fiber holders on the mounting adapter until the desired light output
onto the sample is achieved. Tighten the set screws to secure the holders in place.

3 THE FIBER BUNDLE
The bifurcated glass fiber bundle included with the Light Bias Kit is comb randomized to produce evenly
divided outputs. When light is uniformly focused onto the common end, each leg can transmit 43% of the
total incident energy. The common end and the two legs are all terminated with standard Oriel 11 mm
ferrules.
The fibers in the glass bundle are protected by an interlocking stainless steel sheathing. However, this
bundle is sensitive to position changes. Changing the position of the common end or either leg will
change the output beam distribution and power. To maintain consistent test conditions, avoid movement
of the fiber after the light bias kit has been installed.
Care must be exercised when setting up and storing the glass bundle. Never touch the end faces of the
fiber or allow them to be contaminated by dust or solvents. Incorrect handling will result in breakage of
the glass fibers within the stainless steel sheathing and decreased light output. It is strongly
recommended to save the original packaging for storage.
The minimum bend radius for this fiber bundle is two (2) inches. This bend radius should never be
attempted for the first ¾” after the termination. Minimum bend radius is defined as the smallest radius a
fiber cable can bend before increased attenuation or breakage occurs, as measured from the inside
curvature.

4 COLORED GLASS FILTERS
Oriel colored glass filters serve as broadband, band pass, or long-wave pass filters. A variety of Schott
color glasses covering the visible and near-infrared wavelength regions are offered. These filters are
precision polished for demanding research or OEM applications.
The light bias kit accepts 25.4 mm (1 inch) diameter filters. For easy identification, the filters are
permanently labeled with the glass type. Transmission curves for each filter type listed, as well as
additional filters, may be viewed at www.newport.com/oriel.
To prevent breakage, the glass filters must always be removed from the filter holder prior to transporting
or shipping the light bias kit.
