The present application discloses a nano-textured attenuator which includes a body defining an input aperture, a measurement aperture, and at least one beam dump aperture. At least one coupling fixture may be formed on or positioned on the body, a first nano-textured beamsplitter is positioned within the body and configured to transmit 85% to 99.9999% of an input beam therethrough while reflecting 0.0001% of the input beam to form a partially attenuated beam, at least a second nano-textured beamsplitter is also positioned within the body and is configured to transmit 85% to 99.9999% of the partially attenuated beam therethrough while reflecting 0.0001% of the partially attenuated beam to form an attenuated measurement beam, and at least one camera in communication with the measurement aperture be configured to measure at least one optical characteristic of the attenuated measurement beam.
