OptiLayer:  Your Partner in Design and Post-Production Characterization of Optical Coatings


 Hardware Recommendations

Very good performance can be achieved at ANY computer running Windows 7, Windows 8, or Windows 10 (both 32- and 64-bit versions).

Windows 10 with latest updates is recommended.

To achieve best results we recommend to use (Winter 2020/2021):

  • Processors: Intel i9, i7 series, models with higher clock frequency are better. For extremely high requirements we recommend processors from 10 core Intel i9-10900X up to 18 core Intel i9-10980XE Extreme Edition. In all cases 14 nm or even emerging 10 nm lithography is preferable.
  • AMD processors can also be used.
  • High FSB (Front side bus) speed. Modern Intel processors support 2666 MHz FSB and higher (DDR4 memory).
  • DDR3 or DDR4 fast RAM. Modern computers typically have at least 4 GB. More RAM is better (mainly because Windows OS is more responsible).
  • High-resolution large monitors are recommended. Resolution 1280x1024 is OK, but higher resolutions increase productivity of work very significantly. 1600x1200, 1920x1080 and similar may be optimal for the moment.
  • Multi-Monitor configurations are supported, starting with v. 13.77d monitors with different scaling are also supported (Windows 10).
  • 4K resolution monitors are supported starting with v. 11.65.

Starting from Version 10.48:

OptiLayer software follows the highest modern software standards.

  • Multi-instance modes of all three programs. It is possible to start several copies (instances) of any of these programs simultaneously. Similar to MS Office inactive instances are automatically minimized but can perform background tasks. Different instances should use different Problem directories and respective checks are implemented in order to avoid sharing conflicts.

If you have problems with installation, please read our Frequently Asked Questions (Hardware).

Problem with USB III:

USB III controllers at some modern computers may suspend communications with the hardware key in some quite rare cases.  This problem can be easily fixed:  just try other USB ports! It is better to use not USB III, but classical USB II ports. In cases if your computer has only USB III connections, you can use any cheap USB hub that will automatically downgrade USB III to USB II.

Alternatively it is possible to reprogram the dongle to a different mode that is 100% compatible with all USB III controllers. Please, contact us at This email address is being protected from spambots. You need JavaScript enabled to view it. for more information.
