Celebrating the laser 50th anniversary in Marseille

4 Juin 2010 , Rédigé par JW Publié dans #Fancy lab

From tonight, and ongoing every Friday night in June, a 10W green laser beam will be sent over Marseille historical center. This will redo Fizeau's experiment and measure the speed of light.


See the blog: un laser sur Marseile


Different animations will be distributed along the laser beam path. Posters to illustrate the concepts and applications of lasers, and demonstrations with lasers :

* mini laser show

* laser balloon burning

* schweppes fluorescence

* invisible ink seen with laser

* CD rom physics

World's smallest FCS apparatus

25 Mai 2010 , Rédigé par JW Publié dans #Recent research work

My group has recently developed an integrated system for compact and portative single molecule fluorescence analysis without using any microscope or microscope objective.


The system is based on our patented technology based on a glass microsphere at the end of the optical fiber. The microsphere works as a tiny lens to focus light with focusing capabilities close to that of a high-quality microscope objective.


The system is capable of single molecule fluorescence correlation spectroscopy (FCS) and fluorescence lifetime histograming (TCSPC). The size is roughly that of an A3 format, that makes it the world’s smallest FCS system to date, and much more integration is readily feasible.

This month in Micscape

21 Avril 2010 , Rédigé par JW Publié dans #Fancy lab

My recent Micscape article focuses on the Wild Heerbrugg M20 microscope's binocular head and its effects on imaging. In my opinion, the M20 is simply the best stand for amateur microscopy, balancing optical quality, cost, and size.
