Following strong growth Delta Optical Thin Film A/S is moving into its new purpose-built facilities in DTU Science Park in Hørsholm, Denmark. A new, larger facility became necessary as Delta Optical Thin Film A/S had outgrown its previous residence both in terms of production and office space. At the same time, the new manufacturing building offers a much cleaner production environment.

Delta Optical Thin Film A/S is moving into the new premises and simultaneously expanding its production capacity with new magnetron sputtering coaters, a new improved clean room, a completely new automatic ultrasonic cleaning line, and new dicing equipment.  

Together these investments will not only increase the production capacity but also create a cleaner production environment allowing for higher quality products.

The new building is custom designed to accommodate the very particular needs of manufacturing high-performance optical filters. The two-storey building will allow further considerable growth. Its roof is fully covered with solar panels that will make a sustainable contribution to our energy consumption.

Our new automated ultrasonic cleaning line is completely alcohol-free and allows for the best possible cleaning result without discharging any harmful wastewater. It adheres to Danish environmental protection laws that are among the strictest worldwide.

Since Delta Optical Thin Film A/S was incorporated in December 2014, the company has experienced a doubling of its revenue. This was achieved by expansion of its customer base, expansion into new territories and new applications such as hyperspectral imaging or laser scanning microscopy. This growth was enabled by investments into new coating machines and technologies.
