Downloading and Running Zemax
The class has use of a 25 seat network Zemax key for the duration of the
semester. This software will be necessary to do some of the homework, and will
be invaluable for your project. Use these instructions to install and run the
program.
I)
Get Zemax:
Download and run the Zemax Installer from
http://radiantzemax.com/support/downloads/zemax. Select Zemax 13 Release 2
Service Pack 1, either the 32 or 64 bit version, as appropriate. (The 64 bit
executable is Zemax_2013-10-08_x64.exe for example.) You may also have to
download the Pre-Requisites package, which will check your system for the
necessary Windows features needed for Zemax.
Run the downloaded file to install Zemax.
II)
Tell Zemax where the network key server is:
Navigate to whatever folder you installed ZEMAX in (by default this is
C:\Program Files\ZEMAX) and locate a file called sntlconfig.xml.bak. Rename
this file to sntlconfig.xml, and open it in Notepad. (If your operating system won’t
let you rename the file, copy it to another directory, rename and edit it there, and
copy it back.) Edit the following line:
<ContactServer>
10.0.0.1
</ContactServer>
Replace the default entry 10.0.0.1 with the IP address of your keyserver machine
and save the file.
Note: the IP address of the keyserver is 128.138.189.15
This is a virtual machine, whose only job is to run the keyserver software.
(It can also be found as eceevm-zemax-lic.colorado.edu, but I’m not sure if
Zemax can use that address.)
Note: You will need to either be on the campus, or using CU VPN to get to
the keyserver.
III)
Test the installation:
Start Zemax. You should not need any license code. (If you get an error
message saying that the “key is not found”, check your VPN connection.)
Select ‘file-open’ on the upper left of the main window and open the sample file:
“Samples\Sequential\Objectives\Double Gauss 28 degree field” and follow the
instructions starting on page 8 of “Getting Started With Zemax”. (This pdf can be

If you have problems (likely with the VPN), please inform me ASAP and ask the
people in the IT department across the hall from the ECEE office to check your
VPN connection.
