Description
Our BK7 and K9 optical glass components are precision-engineered to meet the strict requirements of industrial, scientific, and commercial optical systems. Made from high-purity optical-grade glass, these lenses, prisms, and custom optical parts feature excellent transmittance, low thermal expansion, and stable chemical properties, ensuring reliable performance in a wide range of applications.
- BK7 Glass: A crown glass with outstanding optical clarity, low bubble/scratch levels, and excellent transmittance across the visible and near-infrared spectrum. Ideal for general-purpose optics, viewports, and standard lenses.
- K9 Glass: A Chinese equivalent of BK7 with nearly identical optical and physical properties, offering cost-effective consistency for mass production without compromising quality.
- Both materials are polished to high surface quality (up to 10/5 scratch/dig standard) to minimize light scattering and maximize optical efficiency.
We provide custom anti-reflective (AR) coating solutions tailored to your specific wavelength requirements, including:
- Single-layer and multi-layer AR coatings for visible, near-infrared, and infrared spectra
- Ultra-low reflectivity coatings (down to <0.2% per surface) for high-precision systems
- Enhanced transmittance coatings for laser, imaging, and sensing applications
- Durable coatings with anti-scratch, anti-fingerprint, and environmental resistance properties
We manufacture a full range of BK7/K9 optical components to your specifications:
- Lenses: Plano-convex, plano-concave, biconvex, biconcave, cylindrical, and aspherical lenses
- Prisms: Right-angle prisms, roof prisms, dove prisms, and custom beam-splitting prisms
- Windows & Filters: Flat optical windows, bandpass filters, and long-pass/short-pass filters
- Custom shapes and sizes available, with tight tolerances on dimensions, surface flatness, and angular accuracy
These components are widely used in:
- Laser systems and optical instruments
- Medical imaging and diagnostic equipment
- Industrial automation and machine vision
- Consumer electronics and photography optics
- Aerospace and defense optical systems
- Scientific research and laboratory equipment
- OEM/ODM support: Custom design, prototyping, and mass production according to your drawings or requirements
- Quality control: Full inspection with interferometers, spectrophotometers, and microscopes to ensure compliance with your specifications
- Flexible order quantities: From small-batch prototypes to large-scale production runs
- Fast lead times and reliable shipping to meet your project schedules
