Selecting Slide
Projection Lenses When buying a lens, consider features such as focal length (measured in
millimetres), aperture (designed as an f/stop), and the lens design (curved or
flat).
When selecting a lens, remember that the shorter the focal length (i.e., the
smaller the f/number), the brighter the projected image. Also, a curved-field
lens, in combination with cardboard open face mounts from an automated
mounting process, provide superior projection quality. A flat-field lens is the
best choice for glass-mounted slides.
