Nozzle Gem Core

Nozzle Gem Core is a precision-manufactured nozzle component made from high-quality artificial sapphire or ruby crystal materials, offering excellent dimensional accuracy and stability. It features outstanding optical transmittance in the 0.20–5.50 μm wavelength range, with infrared transmission remaining stable under varying temperatures. With high machining precision, the orifice size can be controlled as small as 0.01 mm, ensuring accurate and consistent performance in precision applications. Tight tolerances in diameter, thickness, and surface finish further enhance reliability and repeatability. The material provides exceptional hardness, wear resistance, and chemical stability, enabling long service life even under continuous operation. It is suitable for applications requiring high precision, durability, and stable performance, including industrial spraying systems, optical components, and high-accuracy instrumentation.
