Lambda XL
Extended Life Light Source

The Lambda XL is a broad spectrum, highly stable light source with a ±1% peak-to-peak fluctuation. The connection to the microscope is made through a liquid 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 our popular 300W Lambda LS xenon arc light source. The lamp module is expected to last in excess of 10,000 hours 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 design includes 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. Filters with an absorbing layer are likely to be damaged by the extraordinary power of the Lambda XL and are not recommended for use with this product.

The light intensity can be adjusted to different levels of attenuation. When the optional filter wheel is used, each filter position 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.
