Custom Grown & Machined Silicon & Germanium

Lattice Materials is the largest grower of optical silicon and germanium in the USA, and produces infrared optics, thin film coating sources and custom machined parts to extremely precise tolerances. With the installation of new Czochralski growth facilities in 2019, they can grow ingots up to 22” in diameter with virtually any orientation, optical transmission, and electrical resistivity. Polished blanks, windows, and spherical lenses are manufactured for defense and commercial applications.

Lattice Materials' manufacturing capabilities include basic machining for optical blanks, precision optical curve generation, high-precision polishing, and more. For more than 30 years, they have been the supplier of choice for top defense contractors, Tier 1 automotive suppliers, optical integrators, national laboratories, academic institutions, and semiconductor fabricators.
