LED-based illumination systems for fluorescence applications from Leica

Two new illumination systems from Leica (Wetzlar, Germany) promise superlative image quality for fluorescence applications while being maintenance-free, compact, and easy to operate. Flexible for fluorescence applications in cell biology and neurobiology and for use in imaging facilities, the FLUO LED4000 has five precentered LED modules that can be freely combined for multi-color experiments with different wavelengths. The FLUO LED100 targets applications requiring one fluorochrome only.

The FLUO LED4000 and FLUO LED100 LED illumination systems from Leica (Wetzlar, Germany) promise superlative image quality for fluorescence applications while being maintenance-free, compact, and easy to operate.

Flexible for fluorescence applications in cell biology and neurobiology and for use in imaging facilities, the Leica FLUO LED4000 has five precentered LED modules that can be freely combined for multi-color experiments with different wavelengths. The compact illumination unit is directly connected to the microscope. If an additional wavelength is required, individual LED modules can be exchanged. The narrow-band LED light generates vibrant fluorescent colors and high-contrast images due to the minimization of stray light, as well as being gentle on the sample. The LEDs can be switched on and off and continuously adjusted via the convenient touch panel, enabling reproducible results without sample damage.

The Leica FLUO LED100 targets applications requiring one fluorochrome only. In pathology, cytology, microbiology and immunohistochemistry, where only fluorescein is normally used, this ultra compact and user-friendly LED illumination with its excitation wavelength of 470 nm is ideal. Other wavelengths are available on request. The illumination unit works without a ballast, can be easily connected to all Leica DM1000 through 3000 microscopes equipped for fluorescence, requires no centering and promises ease of use. Thanks to its long life, lamp change is not an issue. The Leica FLUO LED 100 is also an attractive alternative to traditional illumination systems in terms of acquisition cost.

LEDs offer stable excitation intensity, giving reliable quantitative analysis results. They are instantly ready for use after they are switched on, they work for 10,000 hours and are practically maintenance-free.
