Lens Formula To calculate the distance (range) between the projector frontside and the screen (PD)
for a given screen width (SW) use the following formula for
BarcoGraphics 6300 :
Metric system (PD and SW in meter) :
PDmin = 3.374 x SW - 0.115 + 0.0575/SW
PDmax = 4.433 x SW - 0.133 + 0.0556/SW
Inch system (PD and SW in inch) :
PDmin = 3.374 x SW - 4.53 + 89.12/SW
PDmax = 4.433 x SW - 5.24 + 86.18/SW
BarcoReality 6300 :
Metric system (PD and SW in meter) :
PDmin = 3.457 x SW - 0.115 + 0.056/SW
PDmax = 4.542 x SW - 0.133 + 0.054/SW
Inch system (PD and SW in inch) :
PDmin = 3.457 x SW - 4.53 + 86.80/SW
PDmax = 4.542 x SW - 5.24 + 83.70/SW
Lens Cleaning
Procedure
To minimize the possibility of damaging the optical coating or scratching exposed lens
surface we have developed recommendations for cleaning the lens.
FIRST we recommend you try to remove any material from the lens by blowing it off
with clean dry deionized air. DO NOT use any liquid to clean the lenses.
A TorayseeTM cloth is included with the lens kit.
Proceed as follows :

Always wipe lenses with a CLEAN TorayseeTM cloth.
Always wipe lenses in a single direction. Do not wipe back and for-
wards across the lens surface as this tends to grind dirt into the coating.
Do not leave cleaning cloth in either an open room or lab coat pocket
as doing so can contaminate the cloth.
If smears occur when cleaning lenses replace the cloth. Smears are
the first indication of a dirty cloth.
Do not use fabric softener when washing the cleaning cloth or softener
sheets when drying the cloth.
Do not use liquid cleaners on the cloth as doing so will contaminate the
cloth.
