A leading tooling manufacturer in Melbourne recently found the Starrett HE400 system to be instrumental in helping to document their existing range of tools.
Optical comparators, also known as profile projectors or shadow-graphs, are measurement systems that use both lenses and mirrors to project part profiles onto a screen. They are used either to compare projected images of parts to mylar overlays on the screen or alternatively as a way to measure features on parts using a digital readout (DRO) or Tablet device.
The Starrett range of optical comparators or visual measuring devices are manufactured in the Starrett Precision Optical facility in the UK. They renowned the world over for their quality and performance.
Starrett profile projectors are available in both vertical and horizontal formats and in screen sizes up to 750 mm in diameter. Optical comparators are versatile, easy to use and a highly repeatable 2D measuring system. They form the mainstay of any measuring system in most tool rooms.
