Here's a photo I took with Polaroid 667 film and a standard yellow-orange
EtBR filter with a fixed-focus gel documentation camera on a UV lightbox:

The only caveat for this fixed-focus camera is to place spacers under the
camera's hood (cowel) to elevate the camera so that the plane of focus is
~1.5 cm above the transilluminator surface.
