Sample Rotation System

The National Institute of Standards and Technology (NIST) is conducting market research to identify potential sources of commercial products/services for a Sample Rotation System. The system should be an air bearing rotation stage capable of carrying loads in excess of 30 kg, with high rotation speed, and short move-settle time. The system will be used for tomographic measurements. The procurement includes the rotation stage, cabling, control hardware, and control software. • The sample rotation stage should have an air consumption less than 40 SLPM and operate at a pressure of less than 600 kPa. • The rotation stage should have a central clear aperture at least 20 mm in diameter. • The sample rotation stage should have a mass less than 10 kg. • The sample rotation stage should be able to rotate a full 360 degrees. • The sample rotation stage should have a maximum rotation speed of greater than 1000 rotations per minute. • The sample rotation stage should have an axial working load greater than 30 kg. • The sample rotation stage should have a position resolution of better than 2 arcsec. • The sample rotation stage should have a total tilt error of less than 0.5 arcsec and deviations along the axial and radial directions of less than 30 nm.
