Description
UM Optics offers high-quality single crystal silicon wafers designed for demanding mid-infrared optical applications in the 3–5 µm wavelength range. Known for their excellent thermal conductivity, low density, and optical transparency in the infrared spectrum, these wafers serve as ideal substrates for optical windows, filters, laser reflectors, infrared thermometry devices, and infrared lenses.
Our wafers are available in CZ (Czochralski), FZ (Float Zone), and intrinsic silicon types, with diameters ranging from 2-inch to 8-inch. Each wafer undergoes precision-controlled processing—spanning material growth, cutting, polishing, coating, and dicing—to ensure optimal surface flatness and dimensional accuracy. We support both standard and custom specifications to suit diverse industry requirements.
With a vertically integrated production line, we maintain strict quality control, fast turnaround times, and competitive pricing. Whether for small-batch R&D or high-volume manufacturing, UM Optics is equipped to deliver reliable and consistent silicon wafer solutions tailored to your project needs.
