Operating System Requirements And Other Prerequisites

The below chart gives details of system requirements and prerequisites for OpticStudio. 

General notes

  • OpticStudio 15.5 Sp3 was the last to offer both a 32 bit and 64-bit release. OpticStudio 16 and up requires a 64 bit CPU and OS.
  • OpticStudio 16.5 Sp1 was the first release that no longer supports Windows 8.0 and requires 8.1 (due to the switch to .NET 4.6.2).
  • The required .NET and Directx versions will be downloaded automatically when installing OpticStudio if not already on the machine. 
  • Not all the listed releases are still available to download as Zemax phases out and removes releases older than 2 years from the website. 


License Type Compatibility Chart

OpticStudio has changed licensing methods since it was originally released. New licenses have limited backward compatibility. This chart gives a comprehensive list of what versions support each license type.

Mac OS, Linux, and Virtual Machines

Although OpticStudio is intended to run on the Windows platforms listed above, you can run OpticStudio on Linux, Unix, and BSD-based operating systems like Mac OS by using a virtual machine with a Windows environment.
