Flamingo Light Sheet Microscopes Rely on Motion Systems from PI

Flamingo Light Sheet Microscopes Rely on Motion Systems from PI

For the ambitious Flamingo light sheet microscopy project of the research lab around Prof. Jan Huisken at the Morgridge Institute for Research (Madison, WI), Physik Instrumente (PI) supplies linear and rotary stages. These are used for positioning and moving samples in the microscopes. Dr. Thomas Bocher, Head of Segment Marketing Life Science & Microscopy at PI, is delighted that PI was invited to become one of the sponsors of this project: "The use of our precision drives in the Flamingo project is a further proof of their high acceptance even in the most demanding microscopy applications". Key factors are the compact design, reliability, high precision and speed of the motion modules.

"We aim to democratize high-end light microscopy, bringing it to campuses and labs for free," explains Professor Jan Huisken, co-inventor of light sheet microscopy and Director of the Medical Engineering Department at the Morgridge Institute for Research. The project, which is supported by several sponsors, turns the idea of central research facilities upside down and makes travelling with sensitive samples obsolete.

Up to now, two complete systems have been set up; for the coming months and years, Huisken and his team are planning to build several dozen Flamingo-type microscopes. The name derives from the shape of the basic version of the microscope, which reminds us of the bird standing on one leg.

In Light Sheet Fluorescence Microscopy (LSFM), illumination and detection are two separate optical systems that are oriented perpendicular to each other. A laser beam is focused to form a light sheet that illuminates a thin plane within the sample. The fluorescent light that is emitted in this plane is captured and detected by an objective lens. "LSFM is a very powerful and flexible platform for gentle in vivo imaging, offering low phototoxicity and fast image acquisition," Jan Huisken summarizes the advantages of the technology. Because of the gentle "treatment" of the sample, LSFM is predestined for the examination of living organisms.
