How to Read Profile Projector Accuracy Specs
When sourcing a profile projector, the accuracy figures on the specification sheet are the easiest thing to misread. Two suppliers may publish the same number and mean two different things. Understanding the reference point matters more than the number itself.

Profile Projector vs Video Measuring Machine: How to Choose
A profile projector and a video measuring machine (VMM) both perform non-contact dimensional measurement. If the specifications sit in the same class, why two separate product families?

How to Choose Between Horizontal and Vertical Profile Projectors
A profile projector (also known as an optical comparator) comes in two configurations: horizontal and vertical. The two differ in optical path, load capacity, typical workpieces, and application scenarios. Choosing the wrong configuration affects inspection efficiency, measurement accuracy, and even operator posture. This article compares them across six dimensions to support a more informed selection.

What Is a Profile Projector (Optical Comparator)?
In dimensional inspection, the profile projector — known in many markets as an optical comparator — remains one of the most widely used instruments for two-dimensional measurement. With a straightforward structure, simple operation, and reliable results, it is still a standard piece of equipment in metrology labs and production workshops. The two English names, profile projector and optical comparator, refer to the same type of instrument and are used interchangeably.

How Base Structure and Drive System Affect Long-Term Measurement Accuracy in Video Measuring Machines
The measurement accuracy of a video measuring machine depends not only on the optical system and software algorithms—the base structure and drive system play an equally decisive role in long-term accuracy retention. Whether a machine keeps its factory accuracy after years of use or shows noticeable degradation depends largely on the choice of structural material and the design of the drive system.

How Fixtures and Clamping Affect Measurement Reliability in Video Measuring Machines
In video measuring, the way a workpiece is clamped on the measuring stage directly affects the reliability of the measurement results. Many unstable data sets do not originate from the instrument itself, but from improper clamping practices. This article analyzes the influence of fixturing on measurement results from three aspects: clamping stability, workpiece deformation, and datum retention.
