Test discs are small, circular objects used in various fields for quality control, calibration, and testing purposes. They are typically made from a known material or have specific properties that allow them to serve as references in measurements and assessments.
In the optical industry, test discs can contain patterns or coatings used to assess the performance of optical instruments like microscopes, cameras, or telescopes. These discs help evaluate factors like resolution, distortion, and color accuracy.
In electronics and manufacturing, test discs might have precise dimensions or materials to calibrate measurement instruments or verify the accuracy of machinery.
In healthcare, test discs can be used for diagnostic equipment calibration, ensuring that medical devices provide accurate readings.
Overall, test discs are versatile tools used to maintain and verify the accuracy of various equipment and processes in multiple industries.
