Zinc Sulfide (바카라 토토 사이트)
Choose 바카라 토토 사이트 for domes, windows, lenses and other transmissive optics whenever mechanical strength, hardness, or operation in harsh environments is required.
바카라 토토 사이트 is most highly transmissive in the 8 µm to 12 µm spectral range. Its high resistance to rain erosion, high-speed dust, and particulate abrasion, makes it especially suitable for exterior IR windows on aircraft frames.
