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

Fluorescence filters for Point-of-Care

Point-of-Care instruments based on fluorescence detection typically require high performance compact optical filters that can be manufactured cost-effectively in large quantities.

At Delta Optical Thin Film we specialize in all types of filters for fluorometers for Point-of-Care applications. We are using the latest magnetron sputtering technology which ensures cost efficient, high-volume production of durable hard coating filters.

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.
