Our custom optical filters are often found in fluorescence widefield microscopes, recently also in multiphoton laser raster microscopes and in fluorescence spectrometers. After decades of using classical filters with fixed wavelength characteristic, our customers increasingly often ask for continuously variable filters that allow them to design flexible instruments.

Another market trend is Point of Care (PoC) instrumentation that requires very small, yet high-performing custom optical filters in large quantities, and at low price. With our large coating chambers that are equipped with both proprietary hard- and software, we are optimally geared towards these new trends. During the specification and design process we involve in a two-way discussion with our customers and exchange a lot of knowledge.

“Even when presenting our product idea to Delta Optical Thin Film for the first time, I was impressed by the specialist knowledge and focused advice they provided. Their precise knowledge of the coating and filter technologies, as well as the filter simulation capabilities, ultimately led to the production of our Linear Variable Filters. These filters have properties which open up countless fields of application to us. Not only did we receive excellent support from Delta Optical Thin Film in the area of Linear Variable Filters, but also in terms of their optimal application within our optical systems. The quality of our end product is essentially determined by the high quality of the Linear Variable Filters, which continue to conform to our high standards.”
