1. A luminescence reference plate for biological samples, the reference plate comprising:
a support, wherein the support is configured to provide structural support for the luminescence reference plate;
light-producing elements, wherein the light producing elements comprise a layer positioned on the support;
light-blocking elements bounding the light-producing elements, wherein the light-blocking elements comprise a mask;
at least one of a spectral filter layer, an intensity filter layer, and a protective coating layer positioned between the light producing elements and the mask; and
an insulator coupled to the light-blocking elements, wherein the reference plate with an insulator is adapted for use in a thermal cycler having a heated lid.
2. The luminescence reference plate of claim 1 , wherein the light-producing elements comprise a subtraction-based material.
3. The luminescence reference plate of claim 2 , wherein the subtraction-based material comprises Ultem.
4. The luminescence reference plate of claim 1 , wherein the light-producing elements comprise an addition-based material.
5. The luminescence reference plate of claim 4 , wherein the addition-based material comprises photoluminescent-nanocrystal-containing material.
6. The luminescence reference plate of claim 5 , wherein the material comprises quantum dots.
7. The luminescence reference plate of claim 4 , wherein the addition-based material comprises a luminescent-glass-containing material.
8. The luminescence reference plate of claim 1 , wherein the light-producing elements are formed from a multi-layer media between a top portion of a carrier and a bottom portion of the carrier.
9. The luminescence reference plate of claim 8 , wherein the top portion of the carrier forms the light-blocking elements and couples to the insulator.
10. The luminescence reference plate of claim 9 , the bottom portion of the carrier comprises a black background.
11. The luminescence reference plate of claim 10 , wherein the black background comprises an array of recesses in the bottom portion of the carrier, wherein the recesses comprises black paint.
12. A system for calibrating an instrument for thermal cycling of a biological sample, the system comprising:
a thermal cycling device comprising:
a light source;
an optical relay structure;
a detector;
a thermal block;
a heated lid; and
a luminescence reference plate in optical communication with the light source and detector through the optical relay structure, wherein the luminescence reference plate contacts with the heated lid and the thermal block, the luminescence reference plate comprising:
light-producing elements, wherein the light producing elements comprise a layer positioned on the support;
light-blocking elements bounding the light-producing elements, wherein the light-blocking elements comprise a mask;
at least one of a spectral filter layer, an intensity filter layer, and a protective coating layer positioned between the light producing elements and the mask; and
an insulator coupled to the light-blocking elements, wherein the reference plate with an insulator is adapted for use in the thermal cycler with the heated lid.
13. The system of claim 12 , wherein the light-producing elements comprise at least one of a subtraction-based material and an addition-based material.
14. The system of claim 13 , wherein the material comprises at least one of Ultem, photoluminescent-nanocrystal-containing material, quantum dots, luminescent-glass-containing material.
15. The system of claim 12 , wherein the light-producing elements are formed from a multi-layer media between a top portion of a carrier and a bottom portion of the carrier.
16. The system of claim 15 , wherein the top portion of the carrier forms the light-blocking elements and couples to the insulator.
17. The system of claim 16 , the bottom portion of the carrier comprises a black background.
18. The system of claim 17 , wherein the black background comprises an array of recesses in the bottom portion of the carrier, wherein the recesses comprises black paint.
