Calculating the focal length of a lens:

Slide width (mm) x projection distance (mm)

Projection screen width (mm)

= Focal length of lens (mm)

Example:

36 mm x 4500 mm

1800 mm

= 90 mm

Calculating the projection distance:

Focal length of lens (mm) x Projection screen width (mm)

Slide width (mm)

Projection distance (mm)

Calculating the projection screen width:

Slide width (mm) x projection distance (mm)

Focal length of lens (mm)

= Projection screen width (mm)

a = Light angle b= Projection distance c = Slide width d = Focal length
