Abstract: An automated vertical photo densitometer for reading solutions contained in microwell plates. The densitometer utilizes an optical system for minimizing the optical effect of a meniscus on the fluid sample. The invention also discloses a method for determining a centrally located position of a microwell beneath an interrogating beam of light by controlling the size of the light beam and by stepping the well through the beam. A measurement of the light intensity received by a detector is taken at each step. A maximum light intensity value is selected as corresponding to a well position wherein a central area of the fluid sample is substantially within the interrogating beam.
