Tolicore instruments empower researchers with precise measurement solutions, driving innovation in diverse scientific disciplines.
Accurate testing and quality control are ensured by Tolicore instruments, contributing to the efficiency and reliability of semiconductor manufacturing processes.
Tolicore instruments play a vital role in biomedical research, offering precise measurements that support advancements in diagnostics, pharmaceuticals, and life sciences.

Tolicore instruments re-define optical power monitoring. The levels you could only see with a complicated PMT (photomultiplier tube) solution are now visible using a standard PIN-diode-based sensor, thanks to the new approach to detection and low-current-measurements made possible with Tolicore 3700-series instruments and the 4910 optical Si detector.
