Background
2017
As a spin-off from Fraunhofer Heinrich-Hertz-Institute and formerly funded by the Photonics Incubator, our company was founded by Dr. Christian Waltermann and Philip Erik Guehlke in September 2017 in Braunschweig, Germany.
2018
Series-A financing led by Extorel GmbH (Prof. Falk Strascheg), Carl Baasel, and NBank Capital.
2019
Start of new high-volume fs-laser factory and launch of first fiber-integrated spectrometer FBG-Interrogator X100.
2020
Doubling of the fs-laser production capacity and reaching Break-even milestone.
2021
Launch of first multi-channel FBG-Interrogator X400 for simultaneous measurement of up to 120 FBG sensors.
2022
Reaching production milestone of over 1mio. FBG sensors in more than 100tsd. fiber arrays.
2023
Expansion of our manufacturing facility with a dedicated cleanroom for FBG Interrogator production, incorporating cutting-edge lithography-based 3D-manufacturing processes to advance device miniaturization and precision.
2024
Investment in two additional production laboratories, scaling FBG sensor array manufacturing to more than 10 fully-automated production lines and significantly increasing our high-volume production capacity.
