A system and method to extend a dynamic range of fluorescence measurements. The system includes a neutral density filter stack apparatus including a plurality of neutral density filters. The neutral density filter stack modulates the intensity of light from a source. This modulation improves the ability to detect emissions from a wider-range of fluorophore concentrations, specifically addressing inner-filter effects at higher concentrations that would normally require sample dilution. It can be used in a system in which absorbance and fluorescence measurements are carried out, wherein the intensity of the light source is modulated with the apparatus for the fluorescence measurements. In this hybrid system, the stack modulates the intensity of the excitation light source for fluorescence measurements to be made at very low concentrations of analyte. The hybrid system also includes optics for absorbance measurements to be made at concentrations of analyte that are higher than those detected by fluorescence.

METHODS AND SYSTEMS FOR CHARACTERIZING CELL ADHESION
Systems and methods for using machine-learned models to characterize cell adhesion are disclosed. In some embodiments, a machine-learned model includes a first model and, optionally, a second model. A first model may be a convolutional neural network for segmenting images. A second model may be a decision-tree-based and/or ensemble model, such as a random forest model, for example for grading cells or one or more cell cultures. Input for a second model may be based on output from a first model. Timepoint may also be used as an input to a first model and/or second model. Multi-frame images may be used as input to a machine-learned model. In some embodiments, each frame of a multi-frame image is input on a different input channel to a machine-learned model. Decisions about whether to continue culturing or not may be made based on characterization made using a machine-learned model.
