Re: Possible 1930s Olympus Microscope and Objectives

In pictures posted on the Olympus website from the 1930's, all of the microscopes pictured have the same style of focusing knobs. They appear to be of a type of compound with an insert : most likely bakelite. It was not until after W.W. II that they started using solid brass knobs with chrome plati...

Re: 1930s Olympus Microscope and Objectives

That would be an interesting article if it were all true: especially the part about American Optical, which is pure invention or misinterptetation at best.

Re: 1930s Olympus Microscope and Objectives

The overall look of your instrument does not point to the 1930's as a manufacturing date. There are many Japanese instruments that used similar castings or machinings and any of those I have seen that have a similar form with chrome instead of nickel , are from the late 40's on. I'm sure there are ...

Possible 1940s Olympus Microscope and Objectives (Updated)

Hello, I have this Olympus Microscope which I assume is from the 1940s based on the objectives themselves and the manual (which is in Japanese) that has no Hiragana and some kanji which are no longer used. I bought this microscope through an auction and there are 2 Olympus objectives and one other w...

The organism seems to have cilia all around it but have not seen any other features. It can swim but it keeps rolling while doing so. I used a microscope camera and the lowest obj...
