Standard Configurations
Performance Built Into the Material
Inkbit's GRIN lenses are printed with graded dielectric properties encoded directly into the lattice geometry — no post-processing, no adhesives, no assembly.
Wideband Operation
Operational bandwidth extending to 100 GHz — covering X-band through V-band in a single passive optic with no tunable elements.
COT Polymer Material
Cyclic Olefin Thermoset provides 0.04% moisture absorption, consistent dielectric performance across humidity, and a −50 to 105°C thermal window.
Lattice Design
Diamond lattice for V-band precision. Gyroid lattice for thermomechanical robustness at X-band. Each topology engineered for its operating regime.
Industry Compliant
REACH and TSCA listed. Chemical resistance rated excellent against common solvents, oils, and water. Radome options available for field deployment.
Four Lens Variants Two Diameters, Two Lattice Types
Standard Configurations
All configurations use Cyclic Olefin Thermoset (COT) polymer and share the same thermal operating range. Lattice type and unit cell size determine the frequency ceiling.
