The Digital Embryology Consortium is using a Zeiss AxioScanZ1 scanner for the digitisation of collections. Slide scanning commenced in April 2015 at the Blechschmidt Collection, University of Göttingen, Germany.
Note that some collections, including the initial server test images, have come from pre-existing digital images from other scanners that are also included in the image database.
Oversized slides are also scanned and documented at a low resolution using a flatbed scanner, an CanoScan 9000F Mark II.

Only users that have been trained in the Axio Scan.Z1 operation should operate the machine.

The Zeiss AxioScanZ1 scanner is transported to each embryo collection location using a purpose designed transport box. That allows simplified storage and transport of the scanner and all the required accessories. Note that the scanner requires Zeiss technical support for its initial set up at each location.

The space under the transport table is designed for storage of both accessories and the associated computer.

Oversized slides are now also scanned and documented at a low resolution using a CanoScan 9000F Mark II. This is a high resolution CCD scanner, modern LIDE scanners have a very shallow depth of field not suitable for thicker glass slides.
The scanning protocol is transparency positive mode (unsharpen 9600 dpi). A lower resolution flatbed scan is also made to capture the slide label information, that is not visible in the transparency positive mode.
