Corner Cube Prism from China
A solid glass prism with three mutually perpendicular faces that retroreflects incident light parallel to itself regardless of angle of incidence. Falls under HTS 9001.90.50.00 as an unmounted optical prism used in surveying, laser ranging, and alignment systems. Provides position-insensitive retroreflection for distance measurement.

Import Tips
• Provide retroreflection efficiency data across specified angular field
• Solid corner cubes vs hollow designs affect classification and valuation
• Specify aperture size and clear aperture percentage for performance verification
