<DIV><FONT face=Arial size=2>Dear Colleauges, dear Fumio,</FONT></DIV>
<DIV><FONT face=Arial size=2>From your mail one could conclude that
there exist only one cell type , since you
didn't mentioned</FONT></DIV>
<DIV><FONT face=Arial size=2> the cell you used. I
believe you thought only on</FONT></DIV>
<DIV><FONT face=Arial size=2>a cell of 12mm thickness double sector . As
you know I worked many years with the
model E</FONT></DIV>
<DIV><FONT face=Arial size=2>also with interference optics
(unfortunately the Basel Biozentrum has only a XLA and not XLI so in
case of Xli I can't give you advises) that
time much before Beckman sold 3mm DS centerpieces
we cutted the 12mm Epon centerpieces in
</FONT></DIV>
<DIV><FONT face=Arial size=2>2, 3, and 4 mm thin centerpieces
and spacer-rings for them. In case the leaked I added on each
side </FONT></DIV>
<DIV><FONT face=Arial size=2>a double-sector wascher that the
company sells. </FONT></DIV>
<DIV><FONT face=Arial size=2>I don't need to give you
farther explanations, but clear is that the ratio of
cell thicknes goes parallel with the optical signal. <BR>also
in the XLA (absorptio optics ) I use
often thin cells in respect to the Lamberts-Beer
low.</FONT></DIV>
<DIV><FONT face=Arial size=2>With friendly regards ariel.
