Abstract:
1. A laser system for directing light for optical measurements, the laser system comprising: a flow cell connector configured to receive a flow cell configured to provide a sample fluid for measurement; a housing defining an interior chamber, wherein the housing is thermally conductive; a plurality of optical fibers within the interior chamber, the plurality of optical fibers configured to receive light from a plurality of lasers disposed outside the housing, said optical fibers having a plurality of output ends; an optical fiber mount configured to orient the plurality of optical fibers with said output ends positioned to emit light toward said flow cell; a plurality of optical input ports coupled to the housing, the optical input ports configured to interchangeably couple to the plurality of lasers such that the plurality of optical fibers are configured to receive the light from the plurality of lasers through the optical input ports and such that the plurality of lasers are interchangeable with other lasers; a thermoelectric controller thermally coupled to the housing, wherein the thermoelectric controller is configured to maintain the interior chamber at a substantially constant temperature to reduce temperature instability and resulting pointing errors.
