The L.S. Starrett Company has recently expanded the Horizontal X-Axis Travel on its HB400 Benchtop Optical Comparator from 12" to 16" (300 mm to 400 mm), providing users the versatility to measure larger parts on its workstage.

Available with optical edge detection, the HB400 Benchtop model is a workhorse of the broad line of Starrett Comparators, providing performance levels previously only available with floor standing machines. “Customers will surely welcome this enhancement, as the HB400 now has the longest standard X-Axis travel of its comparator class in the industry,” said Mark Arenal, General Manager, Starrett Kinemetric Engineering, Inc.

The Starrett HB400 Optical Comparator features a large 16" (400 mm) diameter viewing screen, the new 16" (400 mm) horizontal travel, a 6" (150 mm) Y vertical travel, a 2" (50 mm) focus travel and a 110 lb. (49.9 kg) workstage load capacity. The HB400 also has rugged all-metal construction with a hard-anodized stage tooling plate, LED profile and surface lighting rated to 50,000 hours,  and touch-screen operation. Featuring a linear encoder glass scale on both X and Y-axes and digital protractor for angle measurement of 1' resolution via Q-axis readout, the HB400 is exceptionally accurate and reliable.

The Starrett HB400 has a single bayonet style lens mounting system that accepts a choice of six fixed interchangeable lenses, as well as OV2 Zoom or TOV2 fixed telecentric magnification video camera systems. The HB400 is available with MetLogix M1 tablet, M2 or M3 measuring software (when using OV2 and TOV2) PC, or digital readout systems.
