      ZEMAX from Optima Research was, until as recently as 2010, installed on several computers at DESY using a decentralised dongle based system of licence verification. Motivated by a number of user requests, several floating-licences have been obtained and are now available centrally, allowing ZEMAX to used on any computer on campus without the obvious inconvenience posed by a dongle based system on a large campus. ZEMAX is only available on WINDOWS.

      Scope and use of the ZEMAX-Licences

      DESY currently holds 5 floating-licences for ZEMAX, valid for all releases since 14th April 2010. This provides users with licences on demand and, whilst allowing ZEMAX to be installed on any number of machines at DESY, it ensures that the maximum number of concurrently running instances of ZEMAX may not exceed the number of licences purchased. It should be noted that, in order to prevent unnecessarily blocking other potential users from obtaining one of the limited number of floating licences, ZEMAX application should always be closed if not in use.

      Supply / Installation of ZEMAX

      The Download and Installation (the key driver software is not necessary) of ZEMAX,as well as following updates, has to be performed via the official website of the producer of ZEMAX. There is no local DESY instance.

      After the installation procedure, ZEMAX has to be registered with the DESY licence server before it can be used. Due to presently limited number of licences, this information can be only given by  the UCO.

      ZEMAX on Notebooks

      In order to use ZEMAX on a Notebook you must ensure that it has a connection to the Licence server at DESY. This means that the Notebook must be either directly connected to the DESY Intranet or the DESY-Intranet must be available via a connection such as VPN. To use ZEMAX  without a intranet connection a Dongle ("Key") must be obtained.


      The ZEMAX documentation will be installed automatically when you install ZEMAX. After starting ZEMAX the documentation can be accessed via the Help-function.


      If you are interested in a training course, please write a mail to it-training@desy.de. This service is exclusively available to DESY employees and its collaborative partners.


      The mailing-list zemax@desy.de has been introduced to provide communication between ZEMAX users, as well as to offer the possibility to send general information concerning the use of ZEMAX at DESY. If you wish to be added to the list, please send a mail to the UCO.


      The supply of the software is described above. It should be noted, that due to the limited amount of central expertise concerning ZEMAX within DESY IT, only rudimentary support can offered. For more detailed information concerning the use of ZEMAX, users should consult the dedicated web sites, ZMAX Users Knowledge Base and the support page from Optima Research.
