the Super Resolution Lens

holders with a scanning width of 5.9

inches.

Image Quality—High-Pass Optics

Ghost image

Epson High Pass Optics includes anti-reﬂ ection optical coatings and a high reﬂ ection mirror.

 There is typically a small percentage of unwanted reﬂ ection with standard CCD glass which can

cause abnormal ghost images. The anti-reﬂ ection optical coating on the CCD cover glass minimizes

this reﬂ ection and reduces ghost images.

 With a higher reﬂ ection rate, ﬁ lm scanning speed is faster.
