About Us

We bring quality to light - worldwide!

Founded in 1986, Instrument Systems has since grown into one of the world’s leading manufacturers of high-precision spectrometers, complex systems and software solutions for spectral light measurement. Our name stands for innovative, top-class light measurement technology and unrivalled specialist knowledge over an extremely broad range of applications.

At our headquarter in Munich and our branches in Berlin and Korea, we develop and produce high-end systems and components for the precise measurement of:

LEDs and LED modules
Solid-state lighting (SSL) for general lighting
LED/OLED displays and automotive interior lighting
Automotive and traffic lighting (Optronik product line)

Instrument Systems has set valid standards for highly accurate spectroradiometric measurement in the LED industry worldwide. To this end, for many years we have been engaged in standardization committees and associations such as DIN and CIE, and cooperate with the leading metrological institutes.

As a successful medium-sized technology enterprise, we have been a member of the Konica-Minolta Group since 2012. Assisted by our distributors with many years of experience, we use the group’s international network to offer our customers optimum support and reliable service at the local level, in particular in Asia.

Many market leaders in the automotive and aviation industry, the lighting industry and consumer electronics place their trust in our measuring systems for the qualification of lighting components and displays. The latter are subject to ongoing development in conformance with the latest regulations and standards. They are used both in the light laboratory and in fast in-line production tests or end-of-line quality assurance.

The Management – united for our customers

Dr. Markus Ehbrecht studied physics at the University of Göttingen. In 1996 he received a PhD in cluster physics and laser spectroscopy at the “MPI für Strömungsforschung”. His industrial activity began as R&D engineer at AGFA and project manager for the development of digital minilabs. From 2006 he was employed as Business Unit Manager at LINOS (later QIOPTIQ) and in 2009 was promoted to the position of Managing Director, responsible for R&D, sales and marketing. Dr. Ehbrecht joined Instrument Systems as Managing Director in January 2014 and was appointed CEO in June 2014.

As of April 2024, Dr. Yuta Yamanoi took over the position of the Managing Director of Instrument Systems to form the new management team together with CEO Dr. Markus Ehbrecht. Dr. Yuta Yamanoi has distinguished himself through more than two decades of professional experience in the field of color and light measurement technology. After eight years in the development department at Konica Minolta Sensing in Japan, in 2016 he transferred to Konica Minolta Sensing Americas Inc. as Business Development Manager. Most recently, he was Senior Manager for Strategic Planning in Light & Display and Color & Appearance division of Konica Minolta Sensing Business Unit in Japan. As a scientist with a PhD in “Earth and Space Sciences” he disposes of extensive know-how in the business area of Instrument Systems.

Our test laboratories – accredited quality in compliance with ISO 17025

The majority of our products is tested by our laboratories, that are accredited with the registration number D-PL-19052-01-00 as test laboratories in compliance with DIN EN ISO / IEC 17025 by the German National Accreditation Body – DAkkS (Deutsche Akkreditierungsstelle). This standard describes the requirements for test laboratories. It is recognized internationally and used by accreditation bodies, authorities and laboratories. The standard defines the requirements for management, as well as for the test and calibration laboratories. The specifications focus on technical details, such as selecting the test procedure, validation, metrological traceability and evaluations of measurement uncertainty.

As a leading manufacturer for light measurement instrumentation, our top priority is to enable you to have maximum trust in our instruments. The accreditation of our test laboratories gives you, our customer, enhanced certainty and guaranteed comparability of measurement results. In this way you can verify to third parties the accuracy of the measurements obtained with the instruments we have tested.

The reference standards we use are traceable to the standards of the national laboratories PTB (Germany) and NIST (USA). Detailed test certificates are supplied with our measuring instruments providing precise terms of reference for traceability.

Technical commitment (memberships, partners)

Instrument Systems is committed to a wide range of technical organizations and conferences. Our cooperation with the CIE (International Committee on Illumination) and its technical working groups is a key commitment in this area. This work has enabled Instrument Systems to make an important contribution to formulation of the CIE 127 Document which defines fundamental recommendations and guidelines for measuring LEDs.
