Photographing through a microscope eyepiece
In the
simplest case, it is possible to take freehand images through a
microscope eyepiece.
Depending
on the type of camera and lens used, with some samples, useable
results may be achieved.
Particularly
for the hobbyist, if only a low quality photograph needs to be
produced, then this method is worth a try

Fundamentally,
it is evident that compact cameras and camcorders with lenses with
smaller front elements that are not telescopic are more suitable. The
best results are provided by very small compact cameras whose lenses
are integrated in the camera body.
SLR
camera lenses cause the most problems.
These
lenses mainly have larger maximum apertures and therefore have large
diameter lens elements.
This
results in peripheral darkening and some aberrations.
Due to the large number of lens elements in the lens unit the image
quality is considerably reduced.
The greatest
problem with freehand photography via a microscope is posed by motion
blurring.
Even
when the hand is very steady, it will still move a few millimetres
here and there.
When
pressing the shutter release button in particular, the camera is
likely to shake.
By
using the shutter delay or self timer function on the camera, the
shutter release is automatically delayed for a few seconds.
This
trick reduces blurring.
Finding the
right position for the digital camera over the microscope’s optical
axis is also not all that easy and can be quite arduous.
Often
it can take several minutes to find the optimum position.
Advantages
of taking freehand photographs over the eyepiece:
• Unbeatable
low price,
as
there is no optical adjustment between the microscope and the digital
camera.
Disadvantages:
-
Long-winded,
unergonomic search for the correct camera position over the
microscope
-
Motion
blurring
-
Peripheral
darkening (vignetting)
-
Serious
image distortions No
optical adaptation to the size of the digital camera’s sensor
Conclusion:
If superior image quality and ease of use is
important to you, then using an LM eyepiece adapter
is the best solution.
The best image quality is achieved by using a digital SLR camera with
Live View function without a lens unit. Only
the camera body is required.
The LM digital adapter projects the image directly onto the camera’s
sensor chip. No unnecessary
lens elements will then be in the light path.
The optimum LM digital
adapter is used according to the size of the camera’s sensor.
