Kodak SO163 new emulsion soon

[Bob Grassucci]

Hi all,
	I just heard form our EM film supplier that Kodak will be changing the 
emulsion on SO163 in 2-3 months.  The idea behind this change is to have a 
quicker pump down time.  We were sent some to test and at first glance it 
seems to be slightly less sensitive to electrons i.e it gives a lower OD at 
the same electron dose.  There did not seem to be any loss in resolving 
power but the plates were lighter.  This is something to be aware of in the 
coming months.
	Bob
