The Balplan was the flagship microscope made by Bausch & Lomb Inc. in the 1970's and 80's, before the merger of their microscope operations into the Leitz / Leica company. Since the Balplan is no longer supported by either company, the knowledge base for maintenance on this fine instrument has defaulted to the community of amateur and professional microscopists.
This site consists of html transcriptions of the original Bausch & Lomb manuals for the Balplan. I am scanning and typing sections and linking in accompanying photographs as time allows. Enjoy!
This (undated) manual probably shipped with each new microscope.
This document is scanned from an n-th generation photocopy of the original, and is barely legible in spots. If anyone has a cleaner copy they'd be willing to have put up, let me know...
