Light detection systems having first and second light receivers, and methods of use thereof

A light detection system comprising:

• first and second light receivers in fixed positions relative to each other, wherein the first and second light receivers are configured to receive first and second beams of light, respectively;
• a plurality of wavelength separators configured to pass light from the first and second light receivers having a predetermined spectral range;
• a plurality of light detection modules, wherein each light detection module is in optical communication with a wavelength separator of the plurality of wavelength separators and comprises a plurality of photodetectors;
• and
• a baseplate for mounting the light detection system, the baseplate comprising:
• first and second stages for mounting the first and second light receivers, respectively, wherein the first and second stages are arranged around a central point;
• and
• one or more heat dissipation openings positioned at a location proximal to the central point.
