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 or Hyperspectral Imaging cameras.

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.

“Edinburgh Biosciences sees DELTA as its closest and most important business partner. The relationship is based on the consistently excellent quality of DELTA’s optical thin film filters which are based on advanced technology and are manufactured to the highest level of performance and reproducibility. Add to that DELTA‘s excellent customer support and our collaboration on multiple technology-based projects in which DELTA’s filters were of central importance. These qualities make DELTA an excellent partner and supplier. We have no hesitation in recommending DELTA as the leading supplier of optical thin film filters.”
