Nikon Instruments Inc., a leader in the development of advanced optical technology, today announced the Nikon Intensilight mercury-fiber illuminator for bioscience and industrial microscopy applications.

The Nikon Intensilight is a pre-centered fiber illumination system with long lamp life and easy lamp replacement which never needs alignment. The Intensilight features a no-flicker, stable light intensity which can be controlled with Nikon's NIS-Elements software.

"Nikon's Intensilight is an ideal choice for stable light intensity which is needed for Epi-Fluorescence applications," said Stan Schwartz, vice president, Nikon Instruments. "The illumination system is an excellent choice for quantitative fluorescence with outstanding transmission at lower UV wavelengths."

The Intensilight features a typical lamp lifetime of 2000 hours as compared to a conventional mercury lamp life which usually lasts approximately 200 hours. A fiber connection means no heat or electrical noise is generated from the lamp and transferred to the microscope body. Stable light intensity, which completely fills the back aperture, is obtained through the use of direct current instead of an alternating current power source.

Nikon's Intensilight includes matched adapters for different families of Nikon microscopes. A built in open-close shutter makes it easy to transfer the illumination source to multiple microscopes on the fly or to shutter the illuminator's light to the microscope specimen, and a neutral density wheel provides intensity control to prevent photobleaching of sensitive specimens while insuring shading free and extremely even specimen illumination. The Nikon Intensilight also delivers consistent reflected light, highly useful for industrial microscope applications. Two sizes of liquid light guide fibers in lengths of 1500mm or 3000mm are available. The Intensilight system include 2 models, a manual version with manual shutter and neutral density selector controls and a motorized and PC controllable version that has an optional desk top control pad for standard use.
