Optical comparators are the mainstay measuring devices for most tool rooms

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.

As well as comparator systems an extensive range accessories and software is available.

Technology

Optical comparators are found in most tool-rooms and workshops and have been the stalwart for many years. They are an easy and quick way to measure angles and other features on tools and cutting edges using clear overlays on the projector screen.

Today’s range of Starrett comparators builds on this tradition by providing robust and rock solid measuring systems. The latest innovations includes fibre-optic edge detection, the option of video-camera systems and Windows-based measurement software. These advancements allow the comparator to be far more repeatable than ever before. The new generation of software enhances productivity and enables the measurement and reporting of complex features and dimensions.

Comparator selection

Horizontal comparators are the most versatile and a frequent choice. Vertical systems are chosen when flexible components such as gaskets, o-rings and flat parts need to be measured.
