Product Description
K9 30mm Sapphire Dome Aspherical Optical Lens
Professional double concave cemented lens designed for superior optical performance in imaging, lighting, and laser applications.
Achromatic Double Cemented Lens Technology
This advanced optical design combines two single lenses made from materials with different refractive indices and dispersion properties. The configuration typically features crown glass on one side and flint glass on the other, creating a low-dispersive positive lens paired with a high-dispersive negative lens to deliver exceptional image quality that surpasses single-lens performance.
Key Features & Benefits
- Superior chromatic aberration correction for multi-color imaging
- Enhanced image quality compared to single-lens designs
- Cost-effective solution for high-performance optical systems
- Wide application range including imaging, lighting, and laser systems
