Deposition Sciences (DSI), a manufacturer of thin film optical coatings, has introduced what it describes as an enhanced capability to manufacture patterned optical filters.

DSI has increased its capacity and resolution with the introduction of a new photolithography production line capable of patterning 200 mm diameter wafers.

The company says the new patterning capability provides an enhanced view or enhanced detection in multi-spectral imaging tasks by fusing together information from different wavelength bands.  

Other applications include satellite imaging, UAV overhead reconnaissance, machine vision, food and industrial inspection, automotive, biomedical sensing, colour filter arrays for CCD and CMOS cameras, and reticles.
