Moving Beyond the Limitations of “Contact-Based” Methods: Why Are Image Measurement Systems Superior
Image measuring instruments feature non-contact measurement, which prevents deformation of the sample caused by applied forces while providing high-precision, high-speed inspection capabilities, ma......
Telecentric Measurement System Selection Guide
Telecentric Measurement Systems use a telecentric optical system to capture the outline (silhouette) of the object being measured and are specifically designed for high-speed, non-contact, high-pre......
How Do Telecentric Measurement Systems Inspect Threads? Five Common Questions
Telecentric Measurement Systems provide an efficient, non-contact, and versatile solution for thread inspection....
Components and Measurement Principles of Spectral Confocal Microscopy Systems
The core components of a spectral confocal microscopy system primarily consist of five key parts: an industrial camera, an APO tube, a point spectral confocal sensing module, an APO objective lens,......
Motorized zoom or manual zoom? 0.7x–4.5x or 0.58x–7.5x?
For offline spot checks with limited budgets, use manual zoom; for automated production lines requiring the program to automatically switch zoom levels, use electric zoom....
What Are ZOOM Lenses and Vari-focal Lenses?
A ZOOM LENS is one that can change its focal length, but may require refocusing during the zooming process; a Vari-focal lens, on the other hand, allows the user to maintain a sharp focus throughou......
Guide to Selecting Single-Excentric and Double-Excentric Lenses
In a double-telecentric system, the principal rays on both the object side and the image side are parallel to the optical axis; in a single-telecentric system, only the object side satisfies the te......
The Difference Between Telecentric Measurement Systems and Projection Measuring Instruments
A projection measuring instrument is an offline sampling inspection device that relies on manual visual comparison; its advantage lies in the intuitive comparison of contours. A Telecentric Measure......
