ZEISS Viluma

Multicolor LED Light Sources for Widefield Fluorescence Microscopy

ZEISS Viluma is a family of light sources for fluorescence imaging that provides you with all the benefits of advanced LED technology: Expect stable illumination to obtain reproducible data. Achieve faster results with high imaging speeds and millisecond switching times. Fine-tune the excitation dose for even your most sensitive samples by precisely attenuating each individual LED. With up to nine illumination channels, image more labels than ever before across the entire spectrum – from UV to far red.

Powerful and Bright

LEDs convert electrical power into light more efficiently than other light sources. With ZEISS Viluma, full excitation intensity is available over the whole lifetime without warm-up times. Improve the efficiency and reproducibility of your imaging experiments, as control over excitation is precise and very stable. You always get enough excitation power and can speed up your image acquisition, if necessary.

Viluma light sources in use with different microscope systems.

Adaptable and Easy to Use

Your ZEISS Viluma light source can house LEDs with a broad variety of wavelengths and intensities. Choose the configuration that exactly matches your applications and budget. With up to nine illumination channels from UV to far red, you are not limited in your choice of labels. All LEDs were specifically selected to deliver exactly the right wavelength and intensity for all your experiments in life sciences research. You control ZEISS Viluma with the familiar ZEN imaging software, the control panel, or the TFT of your ZEISS microscope.

Precise and Gentle

LEDs can be attenuated easily and do not emit unwanted heat or cell-damaging UV light. Your ZEISS Viluma houses specially designed and selected filters that are optimized for excitation of all common dyes and fluorescent proteins with highest accuracy. Your sample is only exposed to the radiation that is needed to excite the fluorescent label. Use ZEN imaging software and hardware triggers to control excitation intensity and wavelength with microsecond precision, perfectly synchronized with your image acquisition. Your sensitive sample is only exposed to light when a frame is acquired.

The ZEISS Viluma Family

Depending on your experiments, the requirements for a light source vary. All ZEISS Viluma light sources are characterized by stable performance immediately after switching on. They are optimally adapted to ZEISS microscopes and provide highest homogeneity across the field of view. State-of-the-art LEDs with high light output guarantee always enough power for imaging dim samples or with high frame rates.
