30 years of expertise in laser technology

With the merger on December 16, 2020, LS Laser Systems and EPP Electronic Production Partners are now going their separate ways, operating as a new brand under the name L-TRIS. LS Laser Systems was acquired in January, EPP Electronic Production Partners in November 2019 and had been part of the Photonics Systems Group since then.

History EPP Electronic Production Partners

The founding years: from hobby cellar to established company

1987: Foundation of EPP Electronic Production Partners in Munich in the hobby cellar of Heinrich Stenger and his brother-in-law Ernst Maikranz
1988: Maikranz leaves the company and Jeri Stenger joins as a partner.
15 years of expertise in the laser trimming business flowed into the newly founded company, thus quickly creating trust on the customer side and building up a network, enabling the young EPP to quickly generate turnover
Expansion of the distributor business: First client was Heraeus Noblelight (laser lamps), for which the distribution in Germany was established.

Establishment of the laser trimming business in Europe

In 1990 EPP became the first exclusive distributor for the laser trimmers, which had been separated from Teradyne (automatic test systems) and were now distributed by TLSI (Telephonics Large Scale Integration, a division of the scanner manufacturer General Scanning).
From this time on, EPP is responsible for the distribution of TLSI laser trimmers in Europe.
TLSI, later renamed GSI Group, was acquired by ESI (Electro Scientific Industries).

From EPP Electronic Production Partners to Photonics Systems Group

November 2019: Sale of EPP Electronic Production Partners to Photonics Systems Group in the course of a succession plan.
Heinrich Stenger already left as managing director at the time of sale, Jeri Stenger and Bryan Burton after successful integration of EPP into Photonics Systems Group in July 2020
Since August 2020 the management is with Markus Nicht
