  • Sutter Lambda-LS Xenon Microscope Light Source

    In response to customer demand, Sutter Instrument Company has developed a stand alone xenon lighting system. The system consists of a xenon arc lamp, cold mirror, 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 175W. This represents more than twice 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).

    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 also can accomodate one of our Lambda 10-2 or Lambda 10-C filterwheels inside the lamp housing. 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.

    • 125W and 175W xenon lamps provide light levels which exceed those of standard microscope fluorescence lamps.
    • Equipped with a cold mirror to eliminate IR heating of down stream optical components.
    • Compact stand-alone lamphousing-power supply enclosure.
    • Pre-aligned bulb eliminates common focusing problems.
    • Integrated hour meter for convenient monitoring of lamp life.
    • Modular construction allows use of optional liquid light guide for flexible direction of light output.
    • Can be directly coupled to many standard microscopes (Nikon, Zeiss, Leica and Olympus) as well as to Sutter Instrument filter wheels, Lambda 10-2 and Lambda 10-C (requires additional adapter, please see adapters section in this catalog)
