Overview

mb-microtec ag is a Swiss microtechnology company based in Niederwangen near Bern, Switzerland. It was founded in 1969 by the physicist Oskar Thüler and is the inventor and, by its own description, the global leader in the development, production and sale of tritium gas light sources. Its core competence is self-luminous technology: tiny glass tubes filled with a small amount of tritium gas, whose emitted electrons excite a phosphorescent coating on the inner wall to produce cold light without batteries, charging or any external energy source. This technology is marketed under the brand trigalight. The company operates several brands. trigalight is the self-luminous technology brand itself. traser is the watch brand built on trigalight, founded as a subsidiary in 1989 after mb-microtec developed and introduced the world's first self-illuminated watch; traser watches are positioned as functional, reliable companions with constant readability in any situation. swisatec offers solutions for increasing the safety of tactical products through the targeted installation of trigalight. Beyond branded products, mb-microtec provides tritium services and tritium trade: it sells tritium in the highest isotope purity for specialised applications including the pharmaceutical industry, and offers tritium services for fusion technology, beta batteries and random number generation for cryptography, as well as tritium-free services such as hermetically sealed glass gas or vapour cells. mb-microtec's history spans more than five decades. After its founding in 1969, it developed its own melting system with rotating light rods in 1970, received its first major order for equipment for the Swiss assault rifle in 1971, and moved into its company building in Niederwangen in 1974. The 1980s brought close industrial collaborations and, in 1988, expansion of distribution through a subsidiary. In 1989 traser swiss H3 watches was founded as a subsidiary. The trigalight brand name was first used for the lights in 2000. New business activities in the medtech sector began in 2011, a new building in Niederwangen was inaugurated in 2018, the company celebrated its fiftieth anniversary in 2019, and in 2021 it commissioned a specially developed, globally unique recycling facility for tritium gas. In 2023 mb-microtec continued to invest. The company remains a private Swiss enterprise headquartered in Niederwangen near Bern, serving customers worldwide through its brands and its tritium technology services.

History

mb-microtec was founded in 1969 by Oskar Thüler, a physicist full of innovative ideas, as mb-microtec Ltd. The company began with the creation of self-luminous light sources, developing and marketing a new technology that works entirely without batteries or charging via external energy sources. In terms of precise mass production and the small size of the resulting product, this technology represented the dawn of a new microtechnical era. In 1970 the company developed its own melting system with rotating light rods. In 1971 it received its first major order: equipment for the Swiss assault rifle. In 1974 it moved into the company building in Niederwangen. In 1980 the first close industrial collaborations began, combining the company's microtechnical and chemical expertise with applied knowledge from different industries and leading to a wide range of successful products. In 1988 distribution was expanded by founding a subsidiary. In 1989 traser swiss H3 watches was founded as a subsidiary company. The development and introduction of the world's first self-illuminated watch by mb-microtec led to the creation of the traser brand. In 2000 the lights were sold under the brand name trigalight for the first time. In 2011 new business activities began in the medtech sector. In 2018 the new building in Niederwangen, Bern, was inaugurated; this unique building fulfils the highest requirements in terms of safety regulations. In 2019 mb-microtec celebrated its fiftieth anniversary. In 2021 the company commissioned a specially developed and globally unique recycling facility for tritium gas. In 2023 mb-microtec continued to invest. Today mb-microtec ag is a Swiss microtechnology company located in Niederwangen near Bern. It describes itself as the inventor and global leader in the development, production and sale of tritium gas light sources. Its brands include trigalight, the self-luminous technology brand; traser, the watch brand with trigalight self-powered illumination technology; and swisatec, which offers solutions for increasing the safety of tactical products through the targeted installation of trigalight. The company also provides tritium trade and tritium services, selling tritium in the highest isotope purity and offering services for fusion, beta batteries, random number generation for cryptography, and tritium-free hermetically sealed glass gas or vapour cells.
