Navitar Lens Models
Navitar zoom lenses let you vary your image size to
completely fill the screen, no matter how unpredictable the
projector-to-screen distance. With Navitar Zoom lenses,
images stay sharp and bright at any point without "pin
cushioning" or "barreling" distortion. A zoom lock screw
allows precise positioning required in multi-image
presentations.
When two or more projectors must be used for a multi-image
slide show, the tilting off-axis of the projectors causes a
perspective distortion called "keystoning." Navitar Keystone
correcting lenses are ideal for these tight throw, rear screen
situations, because they adjust to provide perfect registration
and eliminate keystoning without image distortion.
With their 6.35 image shift, Navitar's XY-PC lenses elimi-
nate keystoning and deliver absolutely perfect registration
in both the Kodak Ektagraphic III and Ektapro slide
projectors. Navitar's PC lenses shift 3.8mm off-axis in any
direction, making them your choice when you need to use
the projector's auto focus feature.
Navitar fixed focal lenth lenses come in 10 models ranging
from 25mm (1") to 355mm (14") and provide razor
sharpness with maximum image brightness throughout the
entire image area of your screen, from edge to edge.
Navitar support brackets stabilize long focal length and
zoom lenses. Their streamlined design requires no special
drilling or tapping of the projector. Support brackets are
required for use with lenses having a focal length of 228mm
and longer, as well as with the150-230mm and 200-300mm
zoom lenses.
For Kodak Ektagraphic III series slide projectors, you will
need Navitar's NSX-III support bracket for Kodak's
Ektapro Series, you will need the Navitar NSX-PRO
support bracket.
