IMT – Precision on Glass

IMT has its roots in the microstructuring of metallic coatings on planar optical substrates. Over the years, we have continually added to this core expertise with complementary technologies.

Our solutions are now used in the semiconductor industry, medical technology, biophotonics, sports optics and optical measurement technology.

In addition to applications focussing on optical functions, the IMT product range also includes components with electronic and/or mechanical functions.

IMT is a leading global player in the development and production of customer-specific microstructures and thin films. Comprehensive services and innovative strength form the foundations of our long-term partnerships. With highly qualified employees and state-of-the-art technologies, we develop and produce key components and ensure constant progress and competitive advantages for our customers.

We take responsibility

IMT takes responsibility for people and the environment in all areas of the business. The way in which we think and act as a company is guided by sustainability. We meet the strictest statutory environmental requirements and ensure compliance with regulations through regular official inspections.

What’s more, we take additional measures which have a sustainable positive effect from both an ecological and economic perspective. For example, by introducing a special heat recovery plant, we have been able to reduce our power consumption by around 30% and heat consumption by around 80%, thereby making a contribution to reducing CO2 emissions.
