Electronic Autocollimator

The U.S. Army TMDE Activity (USATA) has a requirement to procure a brand name purchase of two (2) Electronic Autocollimator that will be used for angle measurements parameter for the calibration of angular gage blocks, optical prisms, optical polygons, and optical wedges. The increased accuracy will eventually allow the APSL to lower its measurement uncertainties for angular calibrations and provide a better Test to Uncertainty ratio for the secondary reference labs. The autocollimators must have an accuracy better than 0.05 arcseconds with a resolution of less than 0.01 arcseconds, and a measurement range greater than ±100 arcseconds. They must also have dual axis measurement capability, have a relatively small footprint: approximately no larger than 12in by 8in, and an ISO 17025 accredited calibration. This item shall be delivered to the Army Primary Standards Laboratory (APSL), Building 5435 Fowler Road, Redstone Arsenal, AL. The Electronic Autocollimator shall include the following specifications or equivalent (if not brand name): Model 229 923 ELCOMAT HR Qty:2 High Resolution Electronic Autocollimator - Dual axis - Fully automatic, software-controlled operations - Resolution: 0.005 arcsec - Absolute accuracy: ±0.01 arcsec over any 10 arcsec range ±0.03 arcsec over total measuring range - Measuring range: +/- 150 arcsec - acquisition range: +/- 600 arcsec - control-/display unit CModul HR - Interface RS 232/USB - software interface INCOLINK - AC-viewfinder prism - DAkkS Calibration
