Establish the desired interface between the Lambda DG-4/5 and your computer.
Each of these steps is discussed in the following sections of the manual.
2.3 Light Guide & Optical Holder Installation
2.3.1 Liquid Light Guide
The light output of the Lambda 10 DG4 is focused onto one end of a liquid light guide. The
output of the liquid light guide can then easily be coupled to your microscope or optical
system using correct mechanical adapter for your microscope. Please note that the light guide
has a minimum-bending radius of 40 mm (about 1.6 inches).
2.3.2 Liquid Light Guide Installation
The liquid light guide should have black sleeves over the ferrules on both ends. These
ferrules, or “end sleeves”, are designed to slide into the mounting flange on the lambda DG-
4/5 cabinet and the output adapter. Insert the end of the light guide into the light guide port
until the top of the black end sleeve is even with the top of the light guide port. Tighten the
locking screw on light guide port to secure the end of the light guide in position. This should
result in maximal or near-maximal light output from the light guide. Minor adjustments up
from this position may improve output; the adjustments can be easily made once the system
is fully installed.

2.3.3 Optical Holder
The free end of the light guide slides into one end of the optical holder tube (shown below).
The other end of the optical holder tube has a UV grade fused silica lens system (in the
“short cup”). By sliding the light guide toward or away from these lenses, the light guide
output can be collimated or brought to a focus. The optical holder, in turn, slides into the
dovetail adapter, which has a “dovetail” collar on one end. This collar is used to fasten the
entire assembly to the microscope system using an adapter (not shown) that is specific to the
microscope make and model. Refer to the documentation included with each microscope
adapter for further installation instructions.
