Converting sensors to detect UV and IR radiation as a low cost alternative to InGaAs cameras
Many of our customers require phosphor coatings on their own sensors to extend the device’s sensitivity further into the UV or IR parts of the spectrum.
By careful selection of phosphor material and grain size, we can work with you to select the most appropriate solution.
Our state of the art facility allows us to rapidly and effectively coat sensors that are supplied by customers in several formats – typically as naked die or mounted onto PCBs – with consistent quality for both small and large production volumes.
We utilise a selection of different coating methods to suit the specific device and application of the customer’s system.
