Tubes (DM R series)
A wide range of tubes for various applications is
available for the LEICA DM series of micro-
scopes.
The abbreviations in the names of the tubes
mean:
HC = Tube system HC, only with HC PLAN and wide field
eyepieces, HC photo adapter components, HC
TV adapters.
F = Phototube, i.e. apart from the binocular obser-
vation part the tube also has a vertical photo exit
for adaption of photomicrographic equipment,
video cameras and microscope photometers.
B = Binocular tube, for visual observation only.
SA = Automatic focus compensation: if the binocular
viewing port set to the individual interpupillary
distance of the user (p. 67), changing optical path
length (which would cause a blurred image when
the magnification was changed and during photo-
graphy) is automatically compensated.

1 BSA 25: binocular tube with focal compensation (shown with pair of eyepieces), 2 HC FSA 25 PR and HC FSA 25 P: binocular
phototubes with (PR) or without (P) back reflection, 3 FSA 25 PE: binocular phototube with provision for adaption of lateral
overlay device, 4 Switch rod for beamsplitter, 5 Mount for photo adapter, 6 Photo adapter clamp, 7 Clickstop for Pol eyepieces,
8 Socket for light trap control cable (PR tube only), 9 Connection for lateral overlay device, 10 Example from HC L tube range
with integrated tube optics (tube HC LVB 0/4/4)

P = This tube is also fully suitable for polarized light
microscopy, as the crosslines in the right-hand
eyepiece are automatically aligned together with
the tube to the polarized light microscope.
E = Provision for lateral adaption of overlay device
(p. 40 and 101).
R = Back reflection of format outlines and measuring
spot possible for photomicrography and photo-
metry.
25 = Eyepieces up to field of view index 25 can be used
(e.g. L PLAN 10x/25))
Outer diameter of eyepieces: 30 mm
V = Variable viewing angle.
L = DM L tube range with integrated tube optics.
