1. A biological analysis system, comprising:
a first element configured to receive excitation light from at least one excitation light source and to communicate excitation light along an excitation light path in a first direction;
a plurality of excitation mirrors arrayed along the excitation light path, wherein each excitation mirror is disposed at an acute angle relative to the first direction and configured to reflect a respective beam of excitation light along a second direction of the excitation light path;
a sample block comprising a plurality of sample receptacles, each sample receptacle positioned to receive a respective beam of collimated excitation light transmitted along the second direction of the excitation light path; and
a plurality of photodetectors, each photodetector configured to receive emission light transmitted in a third direction from a respective sample receptacle, the third direction being at an angle to the second direction of the excitation light path.
