Calculationofthethrowdistancefromthescreensize
NP34ZLlensthrowdistance(inch/m)=H×0.96toH×1.23:40"/1.0m(min.)to314"/7.9m(max.)
NP35ZLlensthrowdistance(inch/m)=H×1.23toH×1.54:51"/1.3m(min.)to392"/10.0m(max.)
NP37ZLlensthrowdistance(inch/m)=H×1.53toH×2.94:63"/1.6m(min.)to748"/19.0m(max.)
“H”(Horizontal)referstothescreenwidth.

Ex.:Throwdistancewhenprojectingona150"screenwiththePX602UL-WH/PX602UL-BKusingtheNP35ZLlens:
Accordingtothe“ScreenSize(forreference)”table(→ page 155),H(screenwidth)=127.2"/323.1cm.
Thethrowdistanceis127.2"/323.1cm×1.23to127.2"/323.1cm×1.54=156.5"/397.4cmto195.9"/497.6cm(becauseofthe
zoomlens).
