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.
“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.”
“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.”
“Delta Optical Thin Film enables our technology and products to really shine and perform to their fullest capabilities. With their unique filter offerings and custom capabilities, Delta Optical Thin Film has been vital to the success of our products. Their focus on customer satisfaction makes sure that we have what we need very quickly.”
“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.”
“Thanks for inventing such a cool product [Linear Variable Bandpass Filter]!”
“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.”
