Single meta optics lenses, fabricated
on silicon wafers, have the potential to
replace the several refractive lenses currently
used in today's mobile devices,
eliminating the so-called " smartphone
camera bump. "
NIR MOE Camera Module
A demonstration of the capabilities of
NILT MOEs is a 940 nm near-infrared
(NIR) wavelength imaging lens with a
single metasurface, used for 3D sensing
and face recognition in smartphones
and driver-monitoring in automobiles.
A complete NIR camera module is
built using a 940 nm single meta optical
element and an NIR sensor. Both demonstrator
and customer-specific metalenses
are currently being prototyped, shipped,
and made ready for mass production.
Figure 4. An image from a near Infrared imaging system using a single meta optical element surface (1M MOE)
designed for 940 nm wavelength. The demonstrated NILT image has excellent resolution for edge-to-edge NIR
imaging and is comparable to images captured with a multi-element refractive lens.
