Greetings,
I was asked this by a colleague and thought I'd pass it along to the list
as it may be of value to others. They are designing a mutli-camera adapter
for a Nikon based TIRF microscope using two emccds. They plan to use 1 lens
to collimate the light out of the microscope and two separate lenses (one
for each camera) to focus on each camera, the second lens will have a
focal length that is twice the first thus giving a 2x mag. I guess they
were thinking f=100 and 200 mm for the lenses. Their questions was, is
there any advantage to using a 2" diameter lens than to a 1" diameter lens,
given that the microscope exit port field of view, and the emccd entrance
port are both less than 1" anyways about 0.7 inches if I remember
correctly. They asked if a larger (2") lens would give less aberration
because you are going "more through the middle" than a 1" lens where you
are getting closer to the edges.
any thoughts?
Thanks!
