Core Material Options: BK7 & H‑K9L Optical Glass

BK7 and H‑K9L are equivalent high‑quality crown optical glass, featuring excellent transmittance across visible and near‑infrared spectrum, low internal bubble and striae level, ideal for optical dome applications.

• Uniform optical performance for imaging and sensor systems
• Good chemical stability and mechanical hardness
• Compatible with multi‑layer AR anti‑reflection coating

Customizable Dome Specifications

We produce optical domes strictly following customer drawings and technical requirements.

• Custom outer radius, inner radius and wall thickness
• Diameter range: small prototype sizes up to large‑format domes
• Tolerance control for optical surface and mechanical mounting interface
• Surface quality meets commercial‑grade optical standards

AR Anti‑Reflection Coating Service

Multi‑layer AR coating can be applied to BK7 / H‑K9L domes to boost light transmission and reduce reflection loss for your target wavelength band.

• Visible‑band AR coating options
• Near‑infrared AR coating upon request
• Coating performance report available on request

Typical Application Scenarios

BK7 & H‑K9L optical domes serve as protective optical windows for a wide range of optical equipment.

• Protective domes for industrial cameras
• Outer protective cover for optical sensor systems
• Inspection & monitoring optical devices
• Laboratory optical instrument assemblies

Manufacturing Workflow

1. Customer drawing & technical requirement review
2. Optical glass blank cutting & CNC machining
3. Grinding for spherical dome surface shaping
4. Precision optical polishing
5. Cleaning, optional AR coating process
6. Inspection: dimension & surface quality testing
7. Anti‑damage clean‑room packaging for shipment
