Sutter Instrument introduces the Lambda XL, a stable, broad spectrum light source with an expected bulb life in excess of 15,000 hours ­ many times that of any comparable light source. The output matches that of 300W arc lamps when new, and this intensity is maintained throughout the life of the bulb with a loss of only 20% expected. The Lambda XL is exceptionally stable, exhibiting fluctuations of merely 1% peak to peak. Unlike arc lamps, the Lambda XL produces no high-voltage pulse, and has no metal-to-glass seals or electrodes to fail.

The compact, stand-alone cabinet design contains bulb, lamp housing, power supply and optics in a single enclosure. The Lambda XL can also accommodate a Sutter filter wheel and SmartShutter within the body of the lamp, making it the right choice for fluorescence imaging applications. The liquid light guide connection assures output uniformity in the field of view.

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