[Nhcoll-l] Recommendation Request: Microscope Slide Scanner

[Lazo-Wasem, Eric]

We have recently completed a project to scan nearly 50K slides using a microscope based slide scanning system.  Ours uses an Olympus BX-51 microscope fitted with a control stage by Objective Imaging using surveyor software.  The camera is a Q-Imaging Fast 1394.  Key for imaging old slides (ours date to 1850s) that are often unstained is having Differential Intereference Contrast lenses.  We also have lenses for reflected light so as to take images of fragments on various slide media (ex. soft corals pieces glued to a cardboard slide).

Objects are scanned as tiles, stitched on the fly to create a single focus plane.  Each tile area can be scanned up to about 150 different depths of focus, with the result 150 planes of stitched images at different focal points.  We render these in Helicon Focus to create an extended focus image.  Stacks can be saved and viewed as a zoom-thru image like a microsope, although most of our images were flatted and viewed as “zoom into” images similar to google maps.

The proof is in the pudding, so to speak.  See examples on our Virtual Microscopy Website.  Contact me for details if this is of interest.

Subject: [Nhcoll-l] Recommendation Request: Microscope Slide Scanner

Dear All,

We are looking into possibly purchasing a microscope slide scanner and have found prices ranging from $30,000 - $125,000 (Zeiss).

We welcome any recommendations regarding microscope slide scanners that you’ve worked with. We would prefer to scan in-house as opposed to sending out.

Thank you!
