Gallium Arsenide (바카라사이트 제작)

Use 바카라사이트 제작 for transmissive and reflective optics in applications where mechanical hardness, mechanical strength, and abrasion resistance are important.

Coherent produces 바카라사이트 제작 with the characteristics required for optical applications by applying laser vacuum calorimetry and other techniques to screen out material with voids, inclusions, or other defects that cause inferior optical performance.

Gallium Arsenide (바카라사이트 제작) Characteristics

Coherent supplies 바카라사이트 제작 substrates of up to 100 mm diameter, and carefully monitors 10.6 µm absorptivity to ensure that thermal runaway and fracture do not occur.
