Leica M-series User Manual 46
★ Three-dimensional observation with 100%
light in the binocular tube.
The HD F features a xed separation ratio of
50% in the binocular tube and 50% in the photo
beam path. This allows the user to conduct
three-dimensional observations of the samples
in the binocular tube, manipulate and edit them
and simultaneously project the image live on
the monitor. Since the sensors of state-of-the-
art cameras are highly sensitive, the exposure
time for most applications is short in spite of
lower light intensity.
Video/Phototubes HD F & HD V
The video/phototubes HD F and HD V are opti-
mized for adapting state-of-the-art digital
cameras to obtain perfect results for image
acquisition. The video/phototubes can be
combined with the binocular tubes and the
ErgoModules™ from the Leica ergonomics line.
A range of high-quality video objectives with
dierent self-magnications and C-mount
allows for the selection of dierent cameras.
Separation ratios
The HD V allows for selecting three dierent
separation ratios:
★ 50% light at all outputs, i.e. 50% light for
stereoscopic observation and recording at
50% light.
★ 100% light in the right eyepiece for moni-
toring the object and 100% light in the
camera to have the maximum light for
the recording under extremely poor light
conditions.
