High volume OEM supply of cost efficient filters for your Point-of-Care fluorometer application

Fluorescence filters for Point-of-Care

Delta Optical Thin Film manufactures all types of filters for fluorometers for Point-of-Care applications.

We are using the latest magnetron sputtering technology from Bühler which ensures cost efficient, high-volume production of durable hard coating filters.

Delta Optical Thin Film builds on more than 30 years of experience in interference filter design and manufacturing. Our business is focused on OEM supply of filters customized for your specific application. We have developed our own thin film filter design software that enables us to design complex filters suited directly for high-volume manufacturing with a consistent performance from unit-to-unit and from batch-to-batch.

Read here how we helped Qlife develope a PoC-instrument for COVID-19 screening in a record time.

Below you can find examples of filters, we have manufactured. These might be a good starting point for evaluating our products before engaging in a customized filter design.
