Quality assurance

Documenting our processes and products

High quality products are the keystone of Delta Optical Thin Film’s success. Our quality management system ensures control and documentation of processes and products throughout the whole design and production process.

We use an ERP system to manage the entire supply chain process including customers and suppliers, order handling, forecasting, reporting and communication.

Our development team is able to make extremely precise predictions of, for example, phase retardation, and uses other dedicated techniques, helping customers make unique instruments.

Our customers and stakeholders expect us to maintain high business ethics, to fulfil our obligations and to act with complete integrity. Our environmental and CSR policy are our tools to fulfill these obligations.

Did you know that once a design as been agreed on, our manufacturing team is able to produce the optical filters in high volumes and at competitive prices? All coatings are thoroughly tested before delivery.
