The inside of my Beseler point light source head is matte black -- and the head has to be focused (moved up and down to get it at the exact height). This is separate from the up & down adjustment of the condenser stage.
The inside of my Beseler CB-7 standard condenser head (older) is white -- to spread out the light evenly on the over-sized CB-7 condenser, I suppose.
The inside of my Beseler 45MXII standard condenser head (newer) is black -- I've never run a comparison test, however.
All original.
Thank you.
I had forgotten this fact/need of point light enlargers.
Cheers
