High performance filters for discerning OEM customers.
WE ARE THE OPTICAL FILTER COMPANY.
We manufacture homogeneous and continuously variable filters from UVA, through VIS and into NIR. Our business is focused on producing high-performance optical filters for discerning OEM customers. Customised OEM filters from Delta Optical Thin Film are designed and manufactured to adhere to any customer requirement or specification for use in the customer’s particular application. This has become increasingly important as the market for advanced imaging or diagnostic technologies incorporating optical filters is growing.
When designing the customised OEM filter, optical parameters such as the angle of incidence, full cone angle and polarisation state are taken into account for a specific filter. Once these parameters are known, mechanical aspects such as width, height and thickness are then specified, including the substrate material, surface quality and clear aperture.
Delta Optical Thin Film manufacture unique customised OEM filters. Highly efficient manufacturing processes and rapid turnaround ensures that customer service is of a high standard, with excellent OEM and technical support assisting the smooth running of the whole process.
If you cannot find the filter you need among our standard products, please do not hesitate to let us know of your requirements. Please fill in our specification sheet as complete as possible and return it to us by email. When specifying your filter, our technical note will help you avoid the main cost drivers in filter design.
