Abstract

This paper describes the fabrication and performance of a testing system for copier and fax lenses in mass production. With the crossed line objects and 2-dim CCD arrays, we could measure the radial and tangential MTF in on-axis and off-axis at the same time. The MTF characteristics of copier and fax lenses measured by this equipment show different results according to the direction of the charge coupled shift register, shutter speed and the amplifier gain of CCDs. This equipment is calibrated by using standard lenses.
