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:
Lens Focal Length/ Projector Distance
•general home projection
•glass mounts
•plastic mounts
•mixed mounts
•
•
•duplicated slides
A curved-field lens works best for:
•embossed cardboard mounts
(Embossed mounts have beveled edges around the aperture. Kodak Premium Processing and Kodak Processing labs provide embossed mounts.)
Use the illustration on the following page to help determine the lens focal length and projector distance.
