Abstract

Apparatus and Methods for measuring light transmitted from a sample. The apparatus may include a stage (123), a light source (103a-103d), and a detector (145a-145d, 160). The stage (123) may be configured to hold a microplate (124) having a plurality of sample wells. The apparatus may be configured to take measurements of one or more of absorbance, scattering, reflectance and luminescence. The apparatus may permit simultaneous measurements of two or more of these properties.
