Abstract
A digital microform imaging apparatus which includes an approximately monochromatic illumination source transmitting an incident light through a diffuse window along a first optical axis of the apparatus. A microform media support is configured to support a microform media after the diffuse window and along the first optical axis. An approximately 45 degree fold mirror reflects the incident light transmitted through the microform media approximately 90 degrees along a second optical axis. An imaging subsystem includes a lens connected to a first carriage which is linearly adjustable approximately parallel with the second optical axis, and an area sensor connected to a second carriage which is linearly adjustable approximately parallel with the second optical axis.

A digital microform imaging apparatus, comprising:
- a chassis including a microform media support structure configured to support a microform media within a plane substantially orthogonal to a first optical axis;
- a fold mirror supported along the first optical axis to reflect light along a second optical axis that is angled with respect to the first optical axis the fold mirror arranged at a substantially 45 degree angle to each of the first and second optical axis;
- a lens supported along one of the first and second optical axis;
- an area sensor supported along the second optical axis;
- a first adjuster for moving the area sensor along at least a portion of the second optical axis;
- and
- a second adjuster for moving the lens along at least a portion of the one of the first and second optical axis.
