Notes
Throw distance calculations are
based on the distance from the outer
end of the lens, which will vary from
lens to lens.
The distance between the front
of the projector chassis and the
outer end of the lens is called lens
extension
. Lens extensions is
measured when the lens is focused
at infinity, and fully extended.
Refer to the projector CAD drawings
for individual lens extension figures.
The 0.38 : 1 fixed lens has no
adjustable shift value. However,
the lens has an inherent offset
depending on image size. See
the UST documentation published
separately on the Digital Projection
website.
The 0.75 - 0.93 : 1 zoom lens has
an additional feature permitting
barrel correction for curved screens.
The front ring of the lens is a
manual control which provides focus
curvature adjustment to correct for
the different focal distances between
center and corner.
