A microplate for making optical measurements is described. The microplate uses two optical flats, which for example can be quartz glass, and a spacer having a plurality of holes defined in the spacer. In use a first optical flat is assembled with the spacer and liquid samples of materials of interest are deposited in one or more of the plurality of holes in the spacer. The volume of each liquid sample is controlled to be sufficient to form a meniscus between the first optical flat and a second optical flat placed over the spacer. The liquid samples do not touch the walls of the holes defined in the spacer. The samples can be examined from either side of the assembled microplate. The microplate can be operated in a horizontal or a vertical orientation. The microplate is easily disassembled, cleaned and made ready for reuse.
