Welcome to Display-Metrology & Systems

We at Display-Metrology & Systems are specialists for all aspects concerning metrology for electronic visual displays and optical metrology in general.



Electronic visual display devices and display screens with Liquid-Crystal-Displays (LCD) and soon maybe with OLED-displays are important interfaces between human beings and their electronic ambient in both work and entertainment situations.


Measurement and evaluation of the electro-optical properties of visual display devices is the basis for the rating of their ergonomic performance (e.g. according to ISO-9241-300) and thus - together with additional technical details as specified in the data-sheet - for purchasing decisions of private and corporate customers.

We are active in the field of display and LCD metrology since 1979 and since then we have provided numerous ideas and contributions to this special field of optical metrology.


In addition we also provide solutions and instruments for a range of problems that can be solved by measurement of optical properties (tilt-bias-angle in LCDs, thickness of translucent layers, refractive indices, etc.).


In the field of display metrology and general optical metrology we provide optimized solutions to our customers in the industry with attractive price-performance ratios.

SMS-1000 - Measurement of Sparkle, DOI,
Reflectance and Transmittance distribution

The SMS-1000 provides a unique basis for comprehensive optimization of display systems with scattering anti-glare layers by evaluation of the three key features: visual sparkle, distinctness of transmitted image and reflectance/transmittance  vs. direction of observation (i.e. scattering distribution functions). 

The SMS-1000 is now available in a second improved version.


DIMOS - numerical simulation of LCDs

The first commercial software for numerical modeling of display systems with LCDs in 1, 2 and 3 dimensions, DIMOS, is now being marketed by DM&S. Technical support, enhancement and maintenance is being provided, just as during the last decade, by Dr. Henning Wöhler and Dr. Johannes Duyster.

In case of interest ask us for a free-of-charge DIMOS evaluation version.


Perform high-resolution BRDF-measurements with your imaging photometer:
the BSDF-Meter is available now on a USB memory-stick.


Response-time measurement and evaluation made easy: the OTR-3 (optical transient recorder) just needs a portable computer with USB-interface, no other supplies required.
