Focusing Device for Time-Lapse Video Recording

Paul Mains

The Biomedical Technical Service Centre at the University of Calgary 
has recently made me a focusing device to be used in conjunction with 
time-lapse video recording with a Nomarski microscope.  The mechanism 
can rotate the fine-focus knob through a range of up to 360 .  The 
upper and lower focal planes for the particular specimen are set and 
the device slowly focuses up and down.  If anyone is interested on 
obtaining one of these, please let me know.  They are willing (in fact 
anxious) to make more and the price is fairly reasonable.
