Hand held Wratten Filter and Haag Streit Slit Lamp Imaging https://www.opsweb.org/forums/posts.aspx?topic=1766103 Sun, 19 Jul 2026 03:29:14 GMT Wed, 24 Jan 2024 16:51:08 GMT Copyright © 2024 Ophthalmic Photographers' Society Hand held Wratten Filter and Haag Streit Slit Lamp Imaging https://www.opsweb.org/forums/posts.aspx?topic=1766103 https://www.opsweb.org/forums/posts.aspx?topic=1766103 Hello All, I was wondering if anybody had experience using a hand held Wratten filter along with the Cobalt blue illumination setting. We have a study that is requesting that we use a Wratten filter but are not getting the results you would get with the newer BX900's that have the filter built. We can usually get nice images that project a green light on our other one. Not sure if its the orientation of where we are placing the filter or if we should crack something open to place the filter into. 

The one we are currently trying to certify with is at a different location and is an older model that does not have the yellow barrier filter built in. 

 

Any suggestions?

Engaging topic.
I would seriously think about writing up and presenting your technique for the 2024 Scientific Session in Chicago!
Thank you,
