A pre-centred mercury-fibre illumination system that never needs alignment has been launched by Nikon Instruments.
The Intensilight provides stable, flicker-free illumination, making it ideal for epi-fluorescence, and its light levels can be controlled via Nikon's NIS-Elements software.
With a typical life of 2000 hours, the Intensilight can be used for approximately ten times longer than a conventional mercury illumination system before lamp replacement is needed.
Furthermore, its fibre connection means neither heat nor electrical noise generated by the lamp can be transferred to the body of the microscope.
Stable light intensity, which completely fills the back aperture, is obtained through the use of direct current instead of an alternating current power source.
"The performance of Nikon's new Intensilight makes it ideal for the epi-fluorescence applications where stable illumination intensity is a must," said Maarten Balzar, product manager for Nikon Instruments Europe.
"With its outstanding transmission at lower UV wavelengths, the new illumination system is also an excellent basis for quantitative fluorescence".
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 move or to shutter the illuminator's light to the specimen.
To prevent photobleaching of sensitive specimens, while ensuring shading free and extremely even specimen illumination, a neutral density wheel is used to control intensity.
Two sizes of light guide fibres, 1500mm or 3000mm, are available.
The Intensilight system comprises two models: a manual version, with manual shutter and neutral density selector controls; and a motorised and PC controllable version that has an optional desk top control pad for standard use.
