Prism array based portable microplate reader
The methods and configurations herein provide for analysis of microplate based assays. Certain aspects include: an optical illumination panel; a plurality of sample wells configured to receive light from the optical illumination panel, and wherein the plurality of sample wells is configured with a first field of view; at least one aperture array configured to isolate directed light therethrough the plurality of sample wells; at least one optical array configured to receive optical information from the plurality of sample platforms, wherein the at least optical array comprises an array of individual microprisms configured with equal apex angles at distal equidistances along a row, wherein the individual microprism apex angles decrease toward the center of the row culminating in at least one flat surface along a center portion of the row; and a detector configured to capture the optical information with a second field of view as provided by the at least one optical array.
1. An optical diagnostic apparatus, comprising:
an optical backlight illumination panel;
a plurality of sample wells configured adjacent the optical backlight illumination panel so as to receive light from the optical backlight illumination panel, and wherein the plurality of sample wells is configured with a first field of view;
at least one hard aperture array configured to isolate a directed light therethrough the plurality of sample wells from the optical backlight panel fixed beneath the at least one aperture array and adjacent the plurality of sample wells;
at least one optical array configured to receive optical information from the plurality of sample wells, wherein the at least one optical array comprises an array of individual microprisms configured with equal apex angles at distal equidistances along a row, wherein the individual microprism apex angles decrease toward the center of the row culminating in at least one flat surface along a center portion of the row;
an optical grating to enable spectral interrogation of the directed light; and
a detector configured to capture the optical information of the directed light received from the optical grating with a second field of view as provided by the at least one optical array.
2. The diagnostic apparatus of claim 1 , wherein the optical array comprises at least one microprism array selected from: an 8×8 and an 8×12 array.
3. The diagnostic apparatus of claim 1 , wherein the optical array comprises a single-stripe-prism array, wherein the single-stripe-prism array is configured as a linear array of individual microprisms with equal apex angles at distal equidistances configured on a row, wherein the individual microprism apex angles decrease toward the center of the row culminating in at least one flat surface along a center portion of the row.
