Patent ID: 8467063

Claim:
An analysis chamber for quiescently holding a biologic sample, which sample has a refractive index, comprising: a first panel; a second panel, at least one of which panels is transparent; and a plurality of lenslets disposed and positionally fixed within the chamber between the first panel and the second panel, which lenslets have a height and a refractive index, which refractive index is different from that of the sample; wherein each of the plurality of lenslets has a characteristic light transmittance pattern, wherein the characteristic light transmittance pattern is the same for each of the plurality of lenslets, wherein the characteristic light transmittance pattern is a function of the refractive index of the lenslets, and wherein the characteristic light transmittance patterns are repeatable and consistent amongst the plurality of lenslets; and wherein the lenslets are all substantially the same shape.
