Its design is based on the use of one elastomeric ring that supports the stylus carrier and allows its movement inside a cubic measuring range of ±3 mm. The position of the probe tip is determined by three low-cost, noncontact, 2D PSD (position-sensitive detector) sensors, facilitating a wider application of this probe to different measuring systems compared to commercial ones. However, several software corrections, regarding the size and orientation of the three LED light beams, must be carried out when using these 2D sensors for this application due to the lack of additional focusing or collimating lenses and the very wide measuring range. The development process, simulation results, correction models, experimental tests, and calibration of this probe are presented. The results demonstrate high repeatability along the X-, Y-, and Z-axes (2.0 µm, 2.0 µm, and 2.1 µm, respectively) and overall accuracies of 6.7 µm, 7.0 µm, and 8.0 µm, respectively, which could be minimized by more complex correction models. info:eu-repo/grantAgreement/ES/CICYT/DPI2002-01258 info:eu-repo/grantAgreement/ES/DGA/T56-23R info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 3.5 2024 CHEMISTRY, ANALYTICAL 38 / 111 = 0.342 2024 Q2 T2 INSTRUMENTS & INSTRUMENTATION 24 / 79 = 0.304 2024 Q2 T1 ENGINEERING, ELECTRICAL & ELECTRONIC 134 / 368 = 0.364 2024 Q2 T2 0.764 2024 Instrumentation 2024 Q1 Analytical Chemistry 2024 Q1 Medicine (miscellaneous) 2024 Q2 Information Systems 2024 Q2 Biochemistry 2024 Q2 Atomic and Molecular Physics, and Optics 2024 Q2 Electrical and Electronic Engineering 2024 Q2 8.2 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Velázquez, Jesús Universidad de Zaragoza (orcid)0000-0001-9617-1004 Torralba, Marta (orcid)0000-0002-3069-2736 Díaz-Pérez, Lucía C.
