A mysterious field microscope - the Chinese TWX-1 (V)
At present one of the most typical mail questions is: "Where can I order a few of those
TXW-1 microscopes" or even "Please send the TWX-1 microscope to my address ..."
But, we are terribly sorry to confirm that at the moment there are very few merchants - worldwide -
who might have one of those micro marvels in stock.
The reasons are quite easily understood: the TWX-1 was made solely in the 1970s,
we think in the years 1971 to 1979. It was produced by the TaiYuan Optical Factory
which had no commercial objective at all. The microscope was provided exclusively
as a mobile hospital equipment to be used by the Chinese army. Top secret.
It took several decades until western specialists and microscope collectors
became aware of the TWX-1. In the years 2008-2010 a limited number of TWX-1 instruments
was offered via Ebay, only from Chinese vendors. But it remains unclear whether the production numbers
were rather low, which percentage of the instruments might have been lost or corroded over the years or
whether thousands of them might still be in possession of the Chinese army. In any case the vendors appear
to have run out of stock at the moment. As a consequence the TWX-1 must be regarded as the rarest and most
collectible field microscope worldwide - which is really bad news for the microscope amateurs
and microscope collectors all over the world.
Until now, no photos are known which might serve to elucidate the production process at the factory
and, of course, it might be extremely interesting to learn how a few western concepts
merged with Chinese production in the 1970s. It must be accepted that the TWX-1 is
far from being merely a copy of a Western product. It is not simply spy work as western cynics
might suspect - instead it appears to be an interesting synthesis of western ideas
into an independent Chinese product.
Only a few of the constructive elements probably have been inspired (or copied) from the
earlier Nikon Model H field microscope.
Among these elements are the roller type specimen holders which allow the object slides to
be moved in (visually) x-direction:
