Starrett manufacture a wide range of optical comparators, also known as a shadowgraph or profile projector that provide a versatile and robust solution for non-contact measurement and inspection, backed by over a century of precision manufacturing expertise. These robust systems, which are ideal for use on the shop floor, project a magnified, silhouette of a component onto a large viewing screen, which is compared to a mylar comparison overlay allowing accurate visual comparisons and dimensional checks.

Using LED profile and surface lighting, profile projectors provide clear and sharp images at different magnifications and provide the ideal tool in quality control (QC), R&D, and manufacturing environments where reliability and precision are critical. Profile projectors are particularly useful for inspecting parts with more complex geometries including pressings, plastic mouldings, electronic components and turned parts.

The range of optical comparators, are designed to meet a wide spectrum of industrial demands. They include horizontal and vertical projection models, either as a compact benchtop shadowgraph or as a floor-standing optical comparator. There are various screen diameters and X-Y stage travel options and a range of interchangeable lenses.

Starrett optical comparators also integrate with modern metrology software and digital readouts, such as MetLogix™ and Quadra-Chek®. These can transform traditional visual inspection into a digital measurement process. There are manual, motor-driven, or fully CNC-controlled workstage options and a wide range of accessories.
