it's been a long while since I posted here... I have a number of
Cambridge Technology 6800HP galvo scanners. as many here know, they
are among the best there is. I have both new and used scanners and I
can sell them for a good price:

Anyway, no claim as to the source or veracity of any of this, however this
link itself links to the original pdf. of the scientists own ...

Where can I obtain/buy a small quantity of metal clad optical fiber?
Preferably ~50/125 and from European distributor or supplyer. I need
it for a small research project, with high temperature fiber
application.

I'm a new member of this group. I work as a Science teacher (Junior
high) in Sweden. We've three JEOL SEM, however only two working at the

keep the microscopes alive. The SEMs' are: a JEOL T200, T330 (not

Lasers that emit ultrashort pulses of light are used for numerous
applications including micromachining, microscopy, laser eye surgery,
spectroscopy and controlling chemical reactions. But the quality of
the results is limited by distortions caused by lenses and other

I'm trying to align a Laserscope 800 series machine. I bought a copy
of the service manual, but in an act of malicious or comedic genius
somebody has removed all the even-numbered pages in the alignment
section! Would anybody be able to send me a copy of these pages?

I am very convinced that he measures right.
I dont know if such a paper as it will be discussed later could be part of a
