Video about Optic Production from Sydor Optics

Nice video (from photonics.com) about the optic production from Sydor Optics.

Outreach scientific videos

If you are interested in Physics, you will like this channel:

Youtube: El origen de la simetría

The project is run by undergrad students of the University of Salamanca. The aim of this channel is providing a source of outreach videos for the general public. The experiments presented in the videos are amusing and the explanation is very clear.

It covers many disciplines: experiments range from the operation principles of a LCD to the explanation of a storm.

Enjoy them!

Summer School of Ultrafast Laser Science & Applications in Menorca (spain)

Between the 10. - 15. June a summer school of ultrafast laser sience and applications is hold in Menorca (Spain). In total there will be 28 hours of lectures about intense short laser technology, attosience, femtochemistry, material processing and biomedecine. The summer school is promoted by the Spanish network of ultrashort ultraintense lasers "Consolider-Ingenio 2010: SAUUL" and mainly organized by CPLU and the optic group of the University of Salamanca.


Registration is now open until 31th March 2012: click here

CLEO 2009 Highlights

Actually, I was looking for something else but found suddenly this video about CLEO 2009. Very nice, enjoy!

Fast Electrically Focus Tunable Lens

When you are reading this post, when you are looking around, your eyes will automatically focus on the spot by reshaping our eye lens. With glass lenses as used in optics, you can achieve that only with moving a lens-system back and forward.

Optotune has introduced now a commercial tunable lens which reshapes its surface and allows continuously focusing between 20mm to 120mm by an external voltage. In the manual version you can even go from -40mm to 40mm, so from concave to convex!




This could find applications in material processing, ophthalmology or microscopy. For further applications have a look at their application homepage

Interesting is also the microscopy application:

Wavelength Conversion Calculator

APE (standing for Angewandte Physik & Elektronik GmbH, a german company in Berlin) has a nice small (and free) wavelength converter on their homepage. It allows you to directly calculate the sum frequency and difference frequency generation, the wavelengths relations in an optical parameteric oscillator (OPO) as well as in coherent anti-stokes Raman scattering (CARS) spectroscopy. Furtermore, the conversion between wavelength, wavenumber, and frequency as well as different characterizations of pulses (dispersion) can be calculated.

The calculator page is in english and very userfriendly. Enjoy.

Prism Awards 2011

The finalists for the prism awards for photonic innovations by the SPIE has been anounced:

Finalists Prism Awards

Take the time to look at the finalists in the 9 different categories. The awards will be presented at the next SPIE Photonics West in January.
