A curved image sensor can improve image quality without expensive and complex lenses. However, until now, most curved sensors have been made with single-chip manufacturing processes. Silina's multi-sensor curving processes open up the ability to scale and reach high-volume markets.
Wilfried Jahn, CTO and co-founder of Silina, commented: 'Our innovation has been driven to unlock the technological barriers of scalability.' He added: 'We can control all the parameters which make the process reliable and repeatable, reducing significantly the cost of production.'
Silina does not design or manufacture image sensors, but offers a service to curve existing flat sensors. Its curving process is the same whatever the sensor format and technology, notably CMOS and CCD. It can be applied to front- and back-side illuminated sensors, and on various spectral bandwidths from ultraviolet, visible to infrared.
Various shapes can be obtained: spherical, aspherical, freeform and custom shapes. The manufacturing process has also been developed to keep the same original packaging used for classic flat sensors, meaning that the mechanical architecture and electronic board remain the same, facilitating the integration of the technology on current production lines.
