Choosing a lens
A number of lenses are available. Which lens you choose depends on the screen size, image aspect ratio, throw distance and light
output. The following table shows all available lenses in order of their throw ratios:
Lens
Focus Range
0.38:1 fixed
1.6m - 5m
0.9 - 1.2 : 1 zoom
0.92m - 10.6m
1.20 - 1.56 : 1 zoom
0.95m - 17.47m
1.50 - 2.00 : 1 zoom
1.24m - 16.4m
2.00 - 4.00 : 1 zoom
1.82m - 41.8m
4.00 - 7.00 : 1 zoom
4.38m - 74.5m
6.9 - 10.3 : 1 zoom
12m - 80m
To choose a lens, calculate the throw ratio required. Allow a tolerance of +/- 3% in the throw ratio calculation.

Notes
Throw distance calculations
are based on the distance
from the outer end of the
lens, which varies from lens
to lens.
The lens extension is the
distance between the front of
the projector chassis and the
outer end of the lens when it
is fully extended.
Refer to the projector CAD
drawings for individual lens
extension figures..
The 1.50 - 2.00 : 1 zoom lens
has a feature that permits
focus correction for curved
screens. The front ring of
the lens is a manual control
that provides focus curvature
adjustment to correct for
the different focal distances
between center and corner.
