10. The Lambda DG-4 is under LOCAL (keypad) control upon start-up, as indicated by the
words “INPUT - MANUAL” on the MAIN MENU (see above). MOVE ON COMMAND is
the active operational mode at start-up, which means that filters are selected by pressing
the numeric keys corresponding to the desired FILTER NUMBER (see EDIT A FILTER
NUMBER definition of this value). The default FILTER NUMBER upon start-up is “0”.
This setting will disrupt the optical pathway within the Lambda DG-4 and prevent any
light output at the light guide port. The “0” FILTER NUMBER serves, then, as a
“shutter” whenever it is selected.
11. Press the “1” key followed by ENTER. This FILTER NUMBER is pre-programmed at the
factory to cause the light to be directed through the FILTER HOLDER that is loaded into
position 1 and then onto the light guide with maximal light output (i.e., minimal
attenuation).
12. Now experiment by selecting FILTER NUMBERS 0 through 4. Anytime you select a
single digit FILTER NUMBER you must complete the entry by pressing the ENTER key
or you must precede the single digit with a “0”. FILTER NUMBERS 0, 1, 2, 3, and 4 are
pre-programmed to correspond with the closed “shutter” and the four FILTER
POSITIONS (with minimal attenuation), respectively.
Now that you have completed the “Make it Glow” section of the manual, you should be
familiar with the basic components and operation of the Lambda DG-4. To get set up for an
experimental application you will need to:

Install the LIGHT GUIDE into the OPTICAL HOLDER (if not already in place).

Install the OPTICAL HOLDER into the microscope using the appropriate adapter (if not
already in place).

Install the desired filters into the FILTER HOLDERS (if not already in place).

Program the desired FILTER NUMBERS.

Establish the desired interface between the Lambda DG-4 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 DG-4 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
