Featuring exceptional surface hardness and chemical resistance, sapphire windows offer broad transmission from UV to MWIR. They are ideal for harsh environments and high-pressure industrial applications.
Performance of sapphire window pieces: high hardness, excellent wear resistance, and heat resistance. The sapphire window is oriented along the Z-axis section, ensuring that the crystal's C-axis is parallel to the optical axis, thereby eliminating the double refraction effect of transmitted light.
