A CONSTANT colour temperature without heat build-up is the main advantage of the LED illumination system used on the new Leica DM4000 B microscope, says the company. The cool and uniform light produced makes the instrument suitable for biomedical and research applications, while the high luminance gives brilliant images with a clear differentiation of the colours in the sample.
Leica's new Leica DM4000 B LED promises uniform illumination for biomedical imaging
Leica says the intelligent automation used in the DM4000 B LED means high-quality, publication ready images and maximum reproducibility for reliable data analysis. The microscope automatically adjusts settings for transmitted light and fluorescence illumination depending on the selection of contrast method and magnification. The most recently used settings are recalled automatically, saving time and allowing the user to focus on the work at hand rather than the instrument.
A more prosaic advantage of the use of light-emitting diode (LED) illumination is that bulb replacement becomes a thing of the past. The LED light source has a lifetime of at least 50,000 hours, which is about 24 years of use at 40 hours per week.
Leica also offers an extensive line of colour and fluorescence cameras and the Leica Application Suite software package, which integrates the DM4000 B and camera into what the company describes as an optimised system for visualisation, storage, and documentation of microscope images.
