Navitar Slide Projection Lenses
Unsurpassed Quality
When you use a state-of-the-art Navitar lens for your
slide presentation, you can be sure that the projected
image you see on-screen is a razor-sharp, accurate
likeness of your original slide image.
Don’t compromise your presentation by using a cheap
plastic lens. Navitar uses only the highest quality materi-
als in the construction of our lenses. Our quality glass
elements and metal barrels, combined with rigid
manufacturing standards and superior, time-proven
optical design, will keep your slide images sharp and
bright and will eliminate the yellowish haze and image
dullness produced by less expensive lenses
We invite you to compare a Navitar lens against any one of
ourcompetitors’products.
We Guarantee Our Workmanship for the
Lifetime of the Lens
Navitar lenses are designed and manufactured in the USA
to be the best in the world. In fact, we have so much confi-
dence in the quality of our workmanship that we’re willing
to back our reputation with a guarantee that lasts the
lifetimeof the lens.
Designed to Let You Read the Fine Print
Navitar’s unsurpassed optical quality ensures that your
slides will be sharp from center to edge with optimum
brightness, color fidelity and image contrast.
Our optical engineers have paid special attention to
guarantee that whites are very white and blacks are very
black. The resulting increase in contrast enhances on-
screen resolution so that text and graphic slides are easier
to read and color slides are more vibrant and alive. You’ll
be able to keep your audience’s full attention from the
beginning to the end of your presentation.

Zoom Lenses
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.
Keystone Correction Lenses
Whentwoor more projectors must be used for a multi-image
slide show, the tilting off-axis of the projectors causes a
perspectivedistortioncalled“keystoning.” NavitarKeystone
correcting lenses are ideal for these tight throw, rear screen
situations,becausetheyadjusttoprovideperfectregistration
andeliminate 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.
Fixed Focal Lenses
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 ofyour screen, from edge toedge.
Lens Support Brackets
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
supportbracket.

We Make Every Size and
Type of Lens
Navitar’s lenses meet any of today’s
toughestprojectionsrequirements.
With a wide selection of fixed focal,
zoom and keystone correction lenses,
Navitar has the correct size lens to

ProjectionCalculator
These charts will enable you to select the Navitar lenses best suited to your audio visual requirements. These projection
chart calculations are based on a 35mm slide format with an aperture that is 1.346 inches wide and 0.902 inches high.
Measurements are made from the film plane to the screen. With Navitar fixed focus lenses, the tolerance in the projection
focal length is +/-1%. Closer matching tolerances are available on request.

Xenon High Intensity Slide Projectors
Navitar’s Xenon slide projectors are six times brighter than conven-

projection distance is greater than 35 feet or ambient light conditions
are uncontrollable. Xenon slide projectors bring slides to life with such
color brilliance, that you can even make your slide presentations with
the room lights on! Slide presentations are more effective, because
visuals have stronger impact and the audience isn’t lost in the depths
of darkened room.
