2mm Diamond Lens

Shaping radio waves with metamaterials.

PereGRIN lenses are passive, multi-band gradient-index lenses for satcom, defense, radar and telecom. They are printed voxel by voxel by Inkbit using Vision-Controlled Jetting, a manufacturing platform invented at MIT.

Realized gain on lenses with apertures beyond 30 wavelengths

0 W

Passive aperture. No phase shifters, no heat sinks, no cooling

100 GHz

Upper working frequency

The Problem Today

Today’s beamforming is reaching its physical limits.

Bandwidth and frequency demands keep climbing. Phased arrays and reflector dishes each solve half the problem. A gradient-index lens combines the strengths of both.

Phased array

Steers electronically with thousands of phase-controlled elements. No moving parts, but expensive, power-hungry and heat-limited. Multi-band needs duplicate hardware.

Reflector dish

Inexpensive and proven, but bulky. Steering means moving the dish, and it tracks one target at a time.

PereGRIN lens

Focuses with a continuous refractive-index gradient obtained by micro-structured internal geometry. Passive, natively multi-band and multi-beam.

Applications

From satellite terminals to vehicle radar.

Ku · Ka

Satcom terminals

Lightweight terminals that track several satellites at once and roam across LEO, MEO and GEO from a single aperture.

10–40 GHz

Defense and counter-UAS

Pencil-thin beams that resist jamming and detection, and battery-powered radar a soldier can carry.

24–90 GHz

5G / 6G and backhaul

High-gain focusing to overcome urban path loss, and power-free relays that densify mmWave coverage.

76–81 GHz

Imaging radar

Sub-degree angular precision in a package compact enough for every vehicle and industrial sensor.

Phase 1

Exploration

Explore what new capabilities our technology enables in your system.

Phase 2

Development

We can co-design a unique lens tuned to your specific requirements.

Phase 3

Prototyping

We can run small production batches for field testing and qualification.

Phase 4

Deployment

Inkbit can handle volume production and become your lens supplier.

Design your product around what we make possible.

From simulation to lens in weeks.

We own the full stack — design software, chemistry and printers — and build every lens in our Massachusetts factory.

Index map to lattice

Our toolchain turns your simulation into a refractive-index point cloud, converts it into a GRIN lattice, and generates voxel-level instructions for the printer.

Ultra-low-loss chemistry

Our proprietary cyclic olefin thermoset (COT) has a loss tangent of 0.0018 at 100 GHz. Vision-Controlled Jetting makes it printable, along with other chemistries that conventional 3D printing can't handle.

Vision-Controlled Jetting

The first additive system that sees what it builds and corrects itself in real time, holding the resolution needed for operation up to 100 GHz.
