Cadmium Posted August 11, 2017 Share Posted August 11, 2017 Here is a graph comparison for the Schott RG715 0.8mm thick.Keep in mind that the bottom flat line is only for lack of lower data, and the 0.8mm thick line continues to taper down, but where it crosses the OD3 line is anyone's guess.

bobfriedman Posted August 11, 2017 Author Share Posted August 11, 2017 well.. it is less than the RG715 @ 2mm.. but greater than RG695.. ok.. well seemed lower to me from a phenomenological perspective. Link to comment
