TRUMPF industrial-grade VCSEL lasers for optical sensing

TRUMPF Photonic Components, a specialist in VCSEL and photodiode solutions for industrial and consumer sensing is showcasing two live demonstrations to show the performance of the single-mode VCSEL solutions at Sensor+Test 2023, 09-11 May, 2023, Nürnberg Messe (Booth 1-156), in Nuremberg, Germany.

One live demonstration will highlight the capabilities for gas sensing in the 760 nm to 766 nm wavelength range. The second will show the precise measurement of particulate matter concentration in the air. The solutions are based on innovative VCSEL technology, such as VCSELs with integrated photodiodes (ViP).

These VCSELs not only emit light, but also detect back-scattered light and therefore allow the self-mixing interference measurement method (SMI). Applications such as optical encoders for speed and distance measurements or particle sensors benefit from this technology. TRUMPF provides customers the option to assess the technical capabilities of the SMI and ViP technology for industrial sensing applications by offering an evaluation board.
