OrthoScan-IMAGER features● Use of a telecentric lens
The OrthoScan-IMAGER uses a telecentric lens patented byiMeasure to obtain orthographic images.

● White and infrared model
Full color (RGB) and infrared (IR) images can be captured
with the one scanner.

● It can capture a large work of art
at a high resolution of 1200 ppi.
If the dimensions of the work exceed the capture range of theA normal optical lensA telecentric lensscanner, it can be scanned section by section. A key featureof orthoimaging is that even such segmented images can bePatented technology

P1

Ortho-photography is a method of projecting images● Normal - vs - ortho-photographic images

whereby images are obtained by projecting collimated
