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


  • My target transmittance has a complicated shape. I cannot create the target using OptiLayer standard tools. Could you help me?

You can create an Excel file, specify your target there by a formula or manually and then import target values into OptiLayer using clipboard (Copy-Paste buttons).

  • I need to cover a glass substrate with two different coatings from front and back sides. What OptiLayer option should I use?

You can specify a stack consisting of one medium (your glass) and specify designs for both sides. Then you can use any of OptiLayer design algorithms. Learn more about stacks…    

  • I need to calculate reflectance and transmittance of my design with 7 decimals, I perform calculation on a very dense wavelength grid (step is 0.000001 nm) and in a extremely narrow spectral range (from 532.599 nm to 532.601 nm). I specify 0.000001 step in the Design > Evaluation report but I see R/T only with 5 decimals. Can I fix this problem somehow.

You should open Analysis > Plot Engine option and specify your spectral range in the Y=f(X) r=tab (from 532.599 to 532.601) and step 0.000001 in the corresponding fields. The number of points will be automatically calculated. After pressing Next button you will see a plot R/T. Click right mouse button and go to Chart Editor. Go to  Export option and choose Data tab there. Choose Excel format and press Save button. After a standard save dialog you will have the Excel file with the results of your calculations. Using Excel tools you can format cells and specify the required number of decimals. 

  • I obtained several solutions of the same design problem and want to compare them with respect to stability to errors in layer thicknesses and refractive indices. It is my understanding of  Error analysis options that I can compare the design stability with respect either errors in thicknesses or errors in refractive indices. Do I understand correctly?

No, you can analyze sensitivity of your designs  to errors in thicknesses and refractive indices simultaneously. In order to do this you have to specify errors in layer thicknesses in one of the tabs Thickness > Coating, Thickness > Materials, Thickness > Thicknesses and errors in refractive indices in Refractive index tab. In the course of calculations OptiLayer will take errors in layer thicknesses on the tab that was opened just before the calculations or before moving to Refractive index tab. For example, if you specified Abs. RMS=1% on Thickness > Coating tab, 2% RMS for all materials on Thickness > Materials tab and 1.5% RMS for all layers on Thickness > Thicknesses tab,  move to Refractive index tab  and specify 0.01 error for all refractive indices then in the course of calculations OptiLayer will take into account 1.5% errors in layer thicknesses and 0.01 offset for all refractive indices.

  • How can I add refractive index file to the Catalog in Optilayer Pro? I have added several materials to the Layers Material database, but they don't show up in the Catalog.

OptiLayer/OptiChar/OptiRE Catalog databases were designed to be read-only. Typically we use already published data and provide corresponding references.

As a solution you can create a Problem Directory that will be used as an additional Catalog (MyCatalog, for example). You can place all your layer materials files there and use "File Transfer" option to take necessary files to your directories. Network shared locations are also supported.

In each new release, we extend data in the Catalog. If you think that your data deserves placing to Catalog and to be accessible by all OptiLayer customers, please, let us know. But in this case we will need to indicate all details related to the data.

  • I have a problem: my hardware key is not recognized by OptiReOpt and Optilayer. This hardware key works perfectly on a different computer. It worked on this computer two weeks before. Can you tell me how to proceed?

According to your notes it looks like your PC problem. There are 2 kinds of hardware keys, and one kind requires "Guardant Drivers". Please, Open "OptiLayer" group in the Start menu and look for "Guardant Drivers" shortcut. Unplug the key and try to reinstall the drivers. If they are installed - uninstall them and install again. After this plug the key again.

In principle, drivers should be installed by default, it is included to general installation procedure of OptiLayer/OptiReOpt. Potentially some maintenance or security procedures may affect this. In particular some antivirus software may be too aggressive and can block correct driver installation.

Be sure that you see the green LED on the key.

If reinstallation of the drivers does not help, unplug another device at the same computer (for example, mouse) and plug the key to this USB. If it works, it means that you have a problem with your USB. Please note, that the non-working ports issue may be connected just with poor internal contact of wires coming from the port to the motherboard. Often this could be easily fixed. Of course, it is easy to buy a USB extension card or a USB hub if necessary.
