The Index is at the end of this first post.
Note: Our UVIR Filters Sticky has more links to filter sellers, data and charts.
If you have a chart not shown here, please post it in this thread or in its own topic. Later I will add it to the Index list.
Many charts here have been provided by Uviroptics (Ebay) and UVR Optics (UVR Defense Tech).
Thank you!

Here is a link to the Schott chart making program. You can enter Hoya data also. Or any data you might happen to have.
Go to Schott's Download Library at this link: http://www.us.schott...load/index.html
There you will see a drop-down menu from which you should select "More Downloads".
You will then see a checkbox list containing the "Optical Filter Glass Calculation Program US".
Check it and a Download button will pop up.
Click the Download button to complete the download of a Zip file containing the program.
The Program is in the form of an Excel spreadsheet, so Excel will be needed to open and use it.
For more on entering Hoya data, see Post #23 below where I have copied some hints from Ebay Uviroptics.
