Abstract
Systems and methods for detecting fluorescent light by providing a filter assembly including an excitation filter and an emission filter.
Claims23
A fluorescent detection system comprising:
- an array of excitation light sources;
- an array of detectors;
- and
- a filter assembly comprising an excitation filter positioned for excitation light from the excitation light sources and an emission filter positioned for fluorescent light from an array of samples,
- wherein the excitation filter and emission filter are positioned substantially parallel to each other, and
- wherein the filter assembly comprises alternating portions of excitation filter and portions of emission filter.
3 more elements
A filter assembly comprising:
- an excitation filter adapted to condition excitation light from an excitation light source;
- and
- an emission filter adapted to condition fluorescent light from a sample,
- wherein the excitation filter and the emission filter are form alternating portions of the filter assembly, wherein the filter assembly is substantially flat, and
- wherein the excitation filter and the emission filter form a lattice with nodes and openings.
