Lambda XL

Extended Life Light Source (Sutter Instrument)

Sutter Instrument introduces the Lambda XL, a broad spectrum, highly stable light source (1 % peak-to-peak fluctuations).

The connection to the microscope is made through a light guide, which assures output uniformity in the field of view.  Two light guide options are available, one optimized for the near UV-visible and the other for the visible-near IR regions.

The output at the end of the light guide  is similar to that of Sutter´s popular 300 W  Lambda LS xenon arc light source.  The lamp module is expected to last more than 10,000 h and maintain at least 50 % of the original intensity.

The compact, stand-alone cabinet design contains the bulb, lamp housing, power supply, and optics in a single enclosure. The new design includes also a filter wheel and SmartShutter™ driver, making it a versatile choice for fluorescence imaging applications.   The Sutter filter wheel with SmartShutter™  or the stand alone SmartShutter™ can be  accommodated within the body of the Lambda XL.

The light intensity can be adjusted to different levels of attenuation.When the optional filter wheel is used, each filter positions can be associated with its own programmable attenuation level, selected every time the filter is called.

Mounting adapters for Nikon, Olympus, Zeiss and Leica microscopes are available.
