Exciter/Barrier Filters https://www.opsweb.org/forums/posts.aspx?topic=435074 Sun, 19 Jul 2026 15:56:17 GMT Thu, 28 Jun 2012 02:46:19 GMT Copyright © 2012 Ophthalmic Photographers' Society Exciter/Barrier Filters https://www.opsweb.org/forums/posts.aspx?topic=435074 https://www.opsweb.org/forums/posts.aspx?topic=435074 I was just wondering how long exciter/barrier filters last? I know it's dependent on use, but we just replaced them a little over a year ago and now we have replaced them again. Any thoughts?

Thanks!!
