This Precision K9 & BK7 Optical Glass Hemisphere Dome Cover is engineered for demanding optical and protective applications. Manufactured from high-grade K9 and BK7 optical glass, these domes offer exceptional light transmission, thermal stability, and dimensional accuracy.
The hemispherical design serves as a durable, low-distortion protective window for sensors, cameras, and lasers. Whether used in underwater photography housings, security surveillance spheres, or LiDAR systems, these covers provide a robust barrier against impact, scratching, and environmental contaminants while maintaining optical clarity.
Key features include tight tolerances on diameter and sphericity, low bubble grade, and excellent homogeneity. Options for anti-reflective (AR) coating, hydrophobic coating, or custom dimensions are available to meet specific wavelength requirements or environmental conditions.
Ideal for OEMs in the defense, automotive, and medical industries, our K9 & BK7 domes combine cost-effectiveness with high-precision performance. Contact us for custom fabrication and coating solutions.
Key Characteristics:
Optical Clarity: High transmittance (>91% in visible light) with excellent homogeneity.
Refractive Index & Dispersion: Moderate refractive index (~1.516) and high Abbe number (~64), meaning low chromatic aberration.
Hardness: Relatively hard (Mohs ~6.5), providing good scratch resistance.
Thermal Stability: Low coefficient of thermal expansion offers improved thermal shock resistance.
Workability: Easier to cut, grind, and polish compared to many specialty optical glasses.
Common Uses: Lenses, prisms, windows in optical instruments, and high-quality decorative items or “simulated crystal.”
