Lambda LS Xenon Arc Lamp
Lambda LS Stand Alone Xenon Arc Lamp and Power Supply

In response to customer demand, Sutter Instrument Company has developed a stand alone xenon lighting system. The system consists of a xenon arc lamp, lamp housing and power supply integrated into a single enclosure. (The arc lamp is of the same construction as that used in our popular Lambda DG-4 wavelength switcher.) The lighting system is compatible with a number of microscope systems (Nikon, Zeiss, Leica and Olympus). The xenon bulb used has an input power rating of 125W. This represents a 60% increase over the typical input power (75W) of epi-fluorescence lamps supplied as standard equipment with most fluorescence microscopes. The Lambda LS can thus deliver higher output in applications where dye concentration is limited by physiological constraints (e.g. access of dye to tissues of interest).

For users who require an even more intense light source, we also offer the Lambda LS with a 175W bulb. In this configuration, the lamp delivers roughly twice the power output of the 125W version. Due to the increased IR output of the 175W Lambda LS, a custom mounted cold mirror is used at the output to reduce the heat transmitted to downstream components. The cold mirror is also available as a factory installed accessory for the 125W Lambda LS.

In addition to higher power, the Lambda LS integrated design offers reduced electrical interference due to start-up arcs and power supply noise. By eliminating a remote power supply, we also eliminate a common failure of standard designs; inability to light due to loss of the insulating characteristics of the high tension line.

Unlike the arc lamps used with most fluorescence microscopes, the bulb in the Lambda LS is pre-aligned using a parabolic mirror, thus producing a uniform, collimated beam of light. In the standard configuration, the Lambda LS uses a xenon lamp capable of producing light output down to wavelengths near 200nm. As with any UV generating light source, this lamp generates significant quantities of ozone and must be used in an adequately ventilated environment. An optional, ozone free bulb is available, which has an attenuated output below 340nm. Both lamps produce relatively uniform output to wavelengths greater than 700nm.

We have designed our new lighting system for maximal flexibility. The optical port is C-mount threaded to accept optional adapters for direct coupling to various commercial fluorescence microscopes. The Lambda LS can also couple directly to the Sutter Instrument Lambda 10-2 and Lambda 10-C filter wheels with one of our many adapters. An optional liquid light guide allows remote positioning of the lamp and relatively low-loss (70%) transmission of the lamp's light into an experimental setup.
