What Is a BaF₂ Plano Convex Lens?
A Plano Convex Lens is an optical lens with:
- One flat surface (plano surface)
- One convex curved surface
This design allows the lens to focus parallel light rays into a single focal point, making it ideal for:
- Light focusing
- Beam collimation
- Image formation
- Infrared signal collection
When manufactured from Barium Fluoride (BaF₂) crystal material, the lens provides excellent infrared transmission performance for specialized optical applications.
