We need to replace our 2 BG38 filters (8.75" x9.75") filters used in front of a Powersmith LED for Visible/IR Luminescence. Our current filters are degrading.
The current filters were purchased at least 6 years ago and I don't have any records from the previous conservation photographer of where they were purchased. Due to these not being on camera filters, I am at a loss as to where to purchase. Any suggestions?
