Abstract: An inspection system for an additive manufacturing machine can include a housing configured to be mounted to an internal construction of the additive manufacturing machine, wherein the housing defines a laser inlet configured to allow a laser beam from a laser of the additive manufacturing machine to enter into the housing, wherein the housing defines a laser outlet configured to allow the laser beam to exit from the housing and to allow reflected light to enter into the housing. One or more detectors is disposed within the housing and configured to receive the reflected light. The system includes one or more optical elements configured to allow the laser beam to pass through the housing from the laser inlet to the laser outlet toward a build area of the additive manufacturing machine and to direct reflected light from the laser outlet to the one or more detectors within the housing.
