Went through some Bausch and Lomb stuff we has yesterday and found this. It's a BL magnifier/microscope that has a scale etched in one of the optic elements, devised in .001" over a -150 +150 (300 thousandths) range, with up to 30x magnification. I have a few of those eye loops with the etched scales but finding this really took my interest.
Does anybody have an idea of when this was made/sold, and if it has a specific application?
Thanks!
