Our Services

Transparent | Agile | High-Class

PHOTOMETRIK GmbH is a service company for various photometric measurements. Our range of standardized measurements covers all from measurement of luminous flux of lamps and luminaires, over classification of photobiological safety, to testing of automotive headlamps as specified by ECE and SAE regulations.
In addition to our measurement services we also offer scientific tool building, expert and review activities and software developement in the field of lighting, light and color.

The following list shows few examples from out portfolio. Feel free to contact us for more specific issues.

Photometric Measurements according to DIN EN 13032
- luminous flux Φ_ν of a wide range of light sources
- luminous efficacy η_ν of a wide range of light sources
- qualification of the energy efficiency class of lamps according to VO EU 874/2012
- goniophotometric measurement of the light distribution of lamps and luminaires to get photometric data
- creation of *.LDT or *.IES files
Measurement of automotive headlamps, motorcycles or tail lamps in accordance to the corresponding ECE regulations
- headlamps: R1, R5, R8, R20, R56, R57, R72, R76, R82, R98, R112, R113, R123
- daytime running lights (DRL): R87
- rear position lamps, stop-lamps and tail lights: R7, R50
- direction indicators: R6, R50
- reflectors: R3, R104
Other measurements
- photobiological safety of lamps and lamp systems IEC 62471 as well as DIN IEC/TR 62778
- escape signs defined in DIN EN 1838
- spatially resolved luminance measurements
- on site measurement of illuminance and luminance

Our processing time is usually around 10 days.
If you should have an urgend project, measurements will be possible within 24 hours, 48 hours or over weekends if it is technically possible.

PHOTOMETRIK

Who we are

PHOTOMETRIK offers various Measurement and Engineering Services in the field of lighting. Our focus is on taking photometric measurements for the preperation of simulation data and data sheets as well as examination of lighting products according to common standards. We are commited to personal support and tailored services.

The company was founded by the three lighting engineers Andreas Groh, Nils Haferkemper and Wjatscheslaw Pepler in July 2013 in Darmstadt (Rhine-Maine area). Our aim is to provide high quality services in fast response for all our products. As a young company we maintain a transparent and open company culture. As a matter of course we are bound to maintain absolute confidentiality and neutrality towards our valued customers.

Measure what can be measured, and make measurable what cannot be measured.

Our Team

Introducing ourselves

Our Team consists of three former research associates of the Laboratory of Lighting Technology at the TU Darmstadt. Despite their different backgrounds and PhD topics we were able to put together an efficient team with complementary expertise. Our core competence is in photometry and spectroscopy and is completed by extensive knowledge on physiology.

Andreas Groh

Andreas Groh studied Electrical Engineering specialized on Electromechanical Design at the TU Darmstadt. In 2007 he started his PhD on “Alternate sensor configuration for luminous flux measurement on High-Power LEDs” where he further examined the topics of light measurement and considerations on measurement uncertainties.

At PHOTOMETRIK his main responsibility is the laboratory and the attached infrastructure as well as qality management.

Nils Haferkemper

Nils Haferkemper sutied media technologies at the TU Ilmenau. After his tenure with Arnold&Richter Cinetechnik, he started his PhD in 2006 on “Brightness perception and pupil performance in the mesopic range” at the Laboratory of Lighting Technology at the TU Darmstadt.

In addition to measurements in our Laboratory he manages R&D as well as marketing at PHOTOMETRIK.

Wjatscheslaw Pepler

Wjatscheslaw Pepler studied microelectronics at TU Darmstadt. Hi PhD thesis started in 2007 at the Laboratory of Lighting Technology at the TU Darmstadt where he did his research on perception of space with various lighting concepts.

At PHOTOMETRIK he carries out measurements as well as financial and legal matters.
