Microscopy imaging
Among other things, an imaging device has a photosensitive array of pixels, and a surface associated with the array is configured to receive a specimen with at least a part of the specimen at a distance from the surface equivalent to less than about half of an average width of the pixels.
1. An apparatus comprising:
a portable housing containing
a lid,
a light source,
a photosensitive array of pixels at a first surface,
the first surface being configured to receive a specimen with at least a part of the specimen at a distance from the first surface equal to less than three times the average wavelength produced by the light source,
a second surface configured to be movable to and from a predefined position relative to the first surface, and
a fluid flow system configured to enable a droplet of the specimen to be applied from a pipette or syringe to the first surface.
2. The apparatus of claim 1 in which the photosensitive array of pixels comprises an imaging integrated circuit.
3. The apparatus of claim 1 comprising a computer-based system programmed to display, analyze, or store high-resolution images of the specimen using information derived from the photosensitive array of pixels.
4. The apparatus of claim 1 in which the specimen comprises a liquid or is suspended or dissolved in a liquid.
5. The apparatus of claim 1 in which the second surface is configured to transmit light.
6. The apparatus of claim 1 in which the light source is positioned to deliver light through the second surface to the first surface.
7. The apparatus of claim 1 in which the light source comprises light-emitting diodes.
8. The apparatus of claim 1 in which the photosensitive array of pixels provides a high resolution image.
9. The apparatus of claim 1 in which the distance from the first surface is less than the average wavelength produced by the light source.
