Choosing a Curved-
or Flat-Field Lens

The lens you select depends on how you use your projector and what type of
slide mount you use. So that you may choose the lens that best meets your
needs, we do not include a lens with the projector.

To obtain the best results of a projected image, insert slides with the emulsion
side toward the projection lens, slide curve toward the light source.

A flat-field lens works best for:

• general home projection

• glass mounts

• plastic mounts

• mixed mounts

• non-embossed cardboard mounts

• rear-projection applications

• duplicated slides

A curved-field lens works best for:

embos

sed cardboard mounts (Embossed mounts have beveled edges

around the aperture. Kodak Premium Processing and Kodak Processing

labs provide embossed mounts.)
