The Lambda LS is a stand-alone illuminator
consisting of a xenon-arc lamp, lamp housing, cold mirror and power supply
in a single enclosure. The Lambda LS is designed to be used with
a liquid light guide which transmits remarkably flat, intense, illumination
to the optical train of the users microscope or other instrumentation.
The lamps cabinet accommodates a standard Sutter Instrument filter
wheel that slides easily in and out of a slot in the light path. If desired,
a second filterwheel can be mounted on the outside of the cabinet. When
used with appropriate adapters, the light guide output is compatible with
most common microscope systems.

Microscope coupling requires special
adapters (not included); please see the adapter section in this catalog.
Unlike the arc lamps used with most fluorescence microscopes,
the 175W xenon bulb is pre-aligned using a parabolic mirror and does not
require alignment, focusing or collimation. In the standard configuration,
the Lambda LS bulb is capable of producing light output from 340nm
to a cutoff of 700nm determined by the cold mirror. An optional enhanced
UV bulb produces output much lower into the UV (cut off near 200nm). As
with any UV generating light source, the optional bulb generates significant
quantities of ozone and must be used in an adequately ventilated environment.
The Lambda LS utilizes a compact design, which places power supply,
lamp house, arc lamp and cold mirror in a single enclosure. This system
eliminates a common failure associated with standard arc lamp designs;
when using a remote power supply aging may lead to a decreased ability
to light the lamp due to loss of the insulating characteristics of the
lengthy high-tension line. As with all our equipment, the power supply
has been designed to minimize electrical noise that can be picked up by
physiological recording equipment.
