WE ARE THE OPTICAL FILTER COMPANY.

Our 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 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.

“I am really impressed with the quality and performance of DELTA Filters. More importantly, our company has a fantastic working relationship with DELTA’s sales and engineering team. They are very customer-focused and went a long way to support our stringent filter requirements with their top-notch engineering professionalism.”
