Microscopy imaging

An apparatus comprising:

• an imaging device comprising a two-dimensional array of pixels at a photosensitive surface, the imaging device being configured to have a specimen stationary, in contact with the photosensitive surface, and within a specimen space adjacent the photosensitive surface,
• a cover having a cover surface,
• a light source, and
• a housing structure supporting the imaging device, the cover, and the light source and configurable back and forth between at least two different configurations including
• one configuration in which (a) the cover surface (i) is supported parallel to and facing the photosensitive surface to define a chamber height and to contain a specimen within a near-field distance of the photosensitive surface, and (ii) is configured to restrict the specimen space, and (b) when the light source is active, light from the light source can reach the specimen and the photosensitive surface through the cover surface, and
• another configuration in which (a) the cover surface is supported at a second height greater than the chamber height from the photosensitive surface, so that (b) the photosensitive surface is exposed to receive placement of the specimen directly onto the photosensitive surface, and
• electronics to cause the imaging device to capture, at one time, information representing a two-dimensional image of the stationary specimen in contact with the photosensitive surface.
