The quick entry interface has been added to the Advanced calculations module. It avoids users having to enter the surfaces of an optical system one by one. It instead allows selecting components from catalogs and laying them out very simply.

Quick entry

Optimization features are part of the Advanced Calculations module. they allow to modify the parameters of a system for reducing aberrations, for reaching a given focal length or magnification... Variable parameters, merit functions as well as boundaries can be selected and defined in the input menu. Optimization sequences are activated by the calculate->optimization menu.

"SCHOTT", "HOYA", "OHARA" as well as generic glass catalogs were already available for simulation on The CDGM glass catalog has been uploaded and completes the list. More than 700 glasses are now usable.

We are happy to have participated in the SFO congress in Nice from the 4th to the 8th of July. This is the most important congress dedicated to optics in France. Many interesting and state-of-the-art presentations were proposed in various fields of photonics. That was the opportunity to get feedback from users and demonstrate the capabilities of the software to scientists involved in photonics.

Users of our "ADVANCED CALCULATIONS" tool dedicated to optical system analysis have now access to components catalogs. They can select components according to criteria and upload them for simulation. This feature simplifies the entry of parameters and allows to simulate off-the-shelf components. Note that links to relevant manufacturer pages are proposed when possible.

CLAVIS was pleased to participate in the Laser world of Photonics exhibition for launching the OPTICAL-CALCULATION software.

This has been a very favorable show. It allowed us to initiate many contacts and to benefit of numerous information and advices to improve our online tool.

Thank you very much to everyone who has expressed interest in us.

Calculations with diffraction gratings were already proposed in the HANDY CALCULATIONS module. Simulations involving gratings and therefore grisms are now part of the ADVANCED CALCULATIONS features. As a result, it is at present possible to analyze many types of real optical systems dedicated to spectral filtering such as spectrometers.


Thursday, April 7 was held the "ELT Instruments Day" in Geneva. This event was organized to inform the ESO suppliers on the business opportunities arising from the construction of the ELT instruments in the coming years.

CLAVIS has participated to this day as provider of the OPTICAL-CALCULATION software. All the speakers made clear and very interesting presentations on the steps already fulfilled and those to come concerning this enormous and very exciting project (ELT). The poster session also allowed to make very relevant contacts. For many of us, this day has been successfull thanks to a perfect organization.
