IR Optics
Our custom sapphire windows are machined from high-purity monocrystalline aluminum oxide (Al₂O₃), tailored for optical systems working under extreme high-temperature, corrosive chemical, abrasive and high-pressure conditions — environments where fused silica and BK7 optical glass fail to maintain consistent optical stability.
We deliver full-spectrum custom sapphire optics solutions machined from high-purity single-crystal aluminum oxide (Al₂O₃), supporting fully personalized geometry, optical curvature, crystal orientation and anti-reflection coatings per customer technical drawings.
Calcium fluoride (CaF2) has excellent transmittance between 250nm and 7um, making them widely used in products such as spectroscopic prisms, windows and lenses
