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.

“DELTA pushes the limits for what is possible with optical thin film filters in order to achieve advanced functionality, high precision and excellent durability. With their capability to design and produce for the most demanding custom requirements it is my pleasure to recommend DELTA.”
