Laurie,

Come to think of it, the arrow is only available on a side-arm 
attachment. Why else would you use an arrow? Of course, now with video 
you have shown that a 'stand-alone' arrow component is useful.

We had a 14-head microscope and had the video camera on an occular head 
three side-arms down from the microscope. It worked well and avoids 
losing the multi-head capacity. You will also have the arrow show up on 
the video. Of course, you will need the tri-tube head or a special 
adaptor for this (we actually had one made by our machine shop). There 
was a bit of a challenge to align the arms to get the same image on the 
monitor as throught the occulars of the main microscope.

We have now a Zeiss microscope that allows video and multihead viewing 
with the video attached to the main microscope.

G'day Tim,
Thanks for your reply. The component you describe sounds like what we
require. Could you please fax or mail me particulars of this unit. Maybe 
it
is something which is available in America but not here.

     My fax number is       + 61 7 4781 5558

Thanks in advance.   Regards,  Laurie.
