Custom-manufactured CO<sub>2</sub> laser optics, available for tunable lasers and instrumentation applications, come in sizes from ½–1 in. OD and 0.070–0.12 in. thick. Featuring laser-grade ZnSe, laser optics have 40-20 scratch-dig surface finish per MIL-PRF-13830 and 1/40 wave max flatness @10.6 µm on 2 faces. Parallelism is 3 arc/mins, and applications include cutting, welding, drilling, marking, and materials processing.
