The dual galvanometer design of the Lambda DG-4/5PLUS allows tuning of the relative
intensities at each wavelength. This adjustment is difficult to obtain in variable wavelength
devices with a single optical path. Unlike monochromators and other wavelength selective
systems, the Lambda DG-4/5PLUS can be used as a source of white light when required.
The optical path subsystem in the Lambda DG-4/5PLUS is arranged so that 2 mirrors, each
mounted on a fast closed-loop servoed galvanometer, can route the collimated output of the
lamp through one of 4 or 5 optical paths (e.g., filter position 1 in the diagram below). Slide-in
filter holders allow 25 mm (1 inch) diameter filters to be introduced in each of the four optical
paths. An additional slide-in filter holder, intended for neutral density filters, is located in a
portion of the optical system common to all light paths. After passing through the filter
positions, the lamp output is focused on a 2-meter long UV (ultraviolet) transmitting light
guide, which acts as a conduit for the output to the microscope. At the output of the light
guide, an optical adapter collects the output and delivers it to the microscope.

Included with each system is a set of four slide-in filter holders. If you wish to quickly replace
any installed filter from a set of many filters, you may wish to order additional slide-in filter
holders.
1.3 Differences between the Standard Lambda DG-4/5 and the DG-4/5PLUS
Both versions of the Lambda DG-4/5 are the same except that the “PLUS” version has the
following advantages:
