For crisp and sharp Images

Some high-quality scanners, flatbed scanners as well as dedicated film scanners, facilitate to adjust the optic’s focus. This means the possibility to offset the focus up to several millimeters above or below the regular focus level. Some scanners feature an automatic focus control system, where others additionally allow the user to set the focus manually.

What do you do with a Focus Control?

You don’t need a focus control, if your originals really lie perfectly flat on your flatbed. However, using filmholders slightly lifts your originals, slide mounts are of different thicknesses and also filmstrips inserted to film scanners are not always perfectly flat, the focus can vary from frame to frame. Setting an appropriate focus leads to crisp and sharp images.

A flatbed scanner offering a manual focus control may also be used to digitize certain three-dimensional objects like coins. Using the SilverFast focus control, the focus can be set so precisely that flatbed scanners can also be used for scientific work, as the example of the bird feather project impressively shows.

"The frame thickness of slides and the thickness of film holders can vary slightly, so the scanner optics may not have the optimal distance for scanning. Some professional scanners from Epson, Nikon, Microtek, PIE and Reflecta allow manually adjusting the focus of the scanner optics up or down by a few millimeters. With SilverFast 8 Focus Control, you will receive perfectly crisp sharpness."
