

Som e light sou rces age; over their life sp an they p rod u ce less light. This aging m ay
not be u niform —a light sou rce m ay p rod u ce p rogressively less light in som e areas of
the sp ectru m bu t not others.

Filters

CCD cam eras are extrem ely resp onsive to infrared (IR) w avelengths of light. To p revent
infrared from distorting the images you scan, use a ―hot mirror ‖ or IR cutoff filter that
transm its visible w avelengths bu t d oes not transm it w avelengths over 750nm . Exam p les
are the Schneider Optics™ B+W 489, w hich includes a mounting ring, the CORION ™ LS-
750, w hich does not include a mounting ring, and the CORION ™ H R-750 series hot
m irror.

Lens Modeling

Any lens su rrou nd ed  by air can be m od eled  for cam era p u rp oses u sing three p rim ary
p oints: the first and  second  p rincip al p oints and  the second  focal p oint. The p rim ary
p oints for a lens shou ld  be available from  the lens d ata sheet or from  the l ens
m anu factu rer. Prim ed  qu antities d enote characteristics of the im age sid e of the lens. That
is,

h

is the object height and

h



is the im age height.

The

focal point

is the p oint at w hich the im age of an infinitely d istant object is brou ght to

focu s. The

effective focal length (f



)

is the d istance from the second p rincip al p oint to the

second focal p oint. The

back focal length (BFL)

is the d istance from the im age sid e of the

lens su rface to the second focal p oint. The

object distance (OD)

is the d istance from the first

p rincip al p oint to the object.
