MECHANISM ANO PRINCIPLE
3. UW·tube
o Inclination 5.2° of prisms
@
and
@
from the optical axis, which is made possible by the
parailel light rays after
@
and
@.
to avoid goast images caused by retlection on the prisms.
• Optical axis of
@,
@
in Photo·tube, though cause haJving, on account of the inclination
of
@
and @,are assumed to be that, if not such halving would be considered, i.e. the
elongation of the axis of
@ @.
• As shown in Fig. 14, the images at OL and ÜR are produced by the parallel ray beams between
@,@)
and
@,
@),
aswellas
@),@)
and
@, @.
• Image position
Qp
of Photo-tube
is
adjusted by changing its tube length using a colllmator, so
that the image is located on the focal point of
@, @.
• Image positions ÜL and ÜR in the binocular body are adjusted by rneans of eyepiece sleeve cover
@,
so that they are parfocal with t.!te image
Qp
of Photo·tube.
• UW-tube permits observation of a wide viewfield of 26.Srnm in dia., using IOX objective.
