GTube Lens Block A10859 Series
These are video lens blocks for use with the infinity-corrected objective
lenses. It has a tube lens with a focal length of 100 mm to form an
image. One side has a male C-mount thread, and the other side has a
female C-mount thread. You can attach a device such as an ICCD or
CCD camera to the side with the male thread.
You can use a C-mount double male thread ring to connect the side
with the female thread to the A10858 stage block.
The tube lens block reduces aberration through the use of an
achromatic lens.

You can calculate the magnification from the imaging lens
focal length (100 mm) and the focal length of the
microscope's objective lens.
Magnification
The light from the sample is collimated by the infinity-
corrected objective lens before it enters the imaging lens.
The imaging lens focuses the image on the focal point.
Even though the beam of light that passes from the infinity-corrected
objective lens to the imaging lens is collimated, the distance between the
lenses must still be kept below a certain limit. This limit (L) can be
calculated from the specifications of the objective and imaging lenses and
the effective area of the sensor.
To avoid vignetting when using the A10859 with objective lens (f1 = 18
mm, NA = 0.25) and a 1/3-inch video camera (
φ = 6 mm), keep the
distance from the objective lens to the A10859 below 100 mm. At this
distance, placing a dichroic mirror between the objective lens and the
A10859 will not have much of an effect on the overall optical
characteristics.
