- Optical Concave Optical Glass Lens
- Double concave - 350mm Focal Length
- High quality, optical lens
- Huge 125mm diameter. Thickness at edge is approximately 12mm. Note, thickness varies as they are not designed to be consistent in that respect.
- Ideal for top spinning.
This is a high quality, optically true lens. Designed for educational purposes, but is also ideal for top spinning.
