Optical System on NextSeq 500/550

• Light-emitting diode (LEDs) are used for excitation on the NextSeq 500/550, although laser diodes are still present for auto-focusing purposes.

• Six cameras are used for capturing signal, and these are housed in independent imaging modules, which also contain the laser diode.

• For additional information on the laser for EH&S (Environmental Health and Safety) purposes, review the Safety Compliance Guide.
