== DScan - a high-performance digital scanning system for entomological collections ==

=== Scanning system hardware ===
* Industrial strength aluminium frame (LWH = 1080 × 1080 × 1500 mm) with linear units
* Servo drives and precision ball screw spindles allow minimum step distance of 0.02 mm at a maximum speed of 100 mm/s
* Effective travel ranges: 600 × 600 mm horizontally (x- and y-axis) and 200 mm vertically (z-axis)
* Operation by PC-controlled console (netbook) with ProNC software (DNC Software Ltd, [http://www.pronc.com www.pronc.com])

=== Camera hardware === 
* Nikon D300 DSLR camera with a 12 megapixel APSC sensor, Voigtländer 90 mm Apo-Lanthar macro lens

=== Lighting ===
* 2 Bowen Gemini 500/500C studio flashes

=== Computer hardware ===
* Workstation equipped with two 2.26 Ghz Intel Xeon processors with 12 MB cache, 24 MB RAM, high-end graphic card, 8 TB HD storage

=== Server infrastructure ===
* Storage server for images, image web publication server, web server

=== Workflow  ===
* Images of a single drawer taken in sequential order as determined by the controlling unit
* Images captured in RAW format, developed using Capture NX2 ([http://www.capturenx.com www.capturenx.com]) and saved as 8- or 16-bit TIFF images
* Captured images assembled (“stitched”) using AutoPano Giga (Kolor, [http://www.kolor.com www.kolor.com])
* Creation of "zoomable" images using Krpano (krpano GmbH, [http://www.krpano.com www.krpano.com])
