TRUMPF showcasing new TruHeat VCSEL modules at LASER World of Photonics

TRUMPF Photonic Components GmbH of Ulm, Germany (part of the TRUMPF Group) – which makes vertical-cavity surface-emitting lasers (VCSELs) and photodiodes for the consumer electronics, datacoms, industrial sensing & heat treatment and automotive markets – is showcasing the latest product developments in its TruHeat VCSEL series as well as live applications of optical sensing in booth 341 (Hall A3) at LASER World of Photonics 2023 in Munich, Germany (25–29 June).

The VCSEL-based heating systems offer direct and homogeneous heat treatment for processes such as drying, sealing or softening. At the LASER show, TRUMPF is demonstrating two new heating solutions for e-mobility. “One example is our next-generation TruHeat VCSEL systems for battery foil drying, offering even higher efficiency and lower power consumption,” says Ralph Gudde, VP marketing & sales. “A small footprint, high process quality, fast processing and lower CO2 emissions are the benefits customers get, when processing using TruHeat VCSEL systems,” he adds.

Live demonstrations: highly precise sensing with VCSELs

Production control and quality management is supported by smart optical sensing solutions to measure speed, distance and position of various materials. Single-mode VCSEL solutions with polarization control are the key enabler for demanding non-contact processing sensor applications due to their superior optical characteristics. A live demonstration highlights the variety of applications that the VCSEL light sources can cover.

In addition to VCSEL components, TRUMPF offers integrated packages for easy and robust handling and the option to customize by integrating optics or electronics. In a second live demo, TRUMPF is showing the real-time measurement of air quality. In cooperation, Bosch Sensortec and TRUMPF developed what is claimed to be the world’s smallest, most highly accurate particulate matter sensor based on a VCSEL with integrated photodiode. The VCSEL solution is a compact, reliable laser source that is maintenance free and insensitive to sunlight.
