I have a Nikon Optiphot-2 bright field and phase microscope. I have been searching for a compatible 2x objective lens that works with the Optiphot-2. I tried several Nikon 2x lens with 160 tuble length but they do not work. I do not have a manual of the Optipjot-2. If any one knows THE TUBE LENGTH OF THE OPTIPHOT-2 MICROSCOPE, please let me know. Also if ANY ONE KNOW WHICH NIKON 2X OBJECTIVE LENS MODEL IS COMPLATIBLE WITH THE OPTIPHOT-2, PLEASE let me know. Does any one have a copy of the MANUAL for OPTIPHOT-2 microscope? I would like to have a duplicate copy of such a manual and I will pay for the cost of duplication and mailing service. Thank you very much for your assistance.

The Nikon Optiphot 2 tube length is 160 mm DIN finite. It is a 1990 vintage microscope. Any objective lens with the standard RMS thread, -160 engraved on it will work. It will not work with other brnads with the infinity symbol engraved on it or infinity tube length Nikon 200 mm, CFI60 objectives for 2000 vintage to present microscopes. - Lawsen Lew

We have misplaced the charger for our National Optical Model 109-L microscope. Could you describe to me the charger that is packed with that model so we might be able to identify it from our miscellaneous chargers?
