Meopta is capable of producing the highest quality spherical lenses, dublets and complex lens assemblies as well as spherical mirrors with metallic or dialectric reflectivity. Spherical lenses are most common optical elements used either individually or in various sets.
- Plan-convex, plan-concave, bi-convex, bi-concave and menisc lenses
- Cemented doublets and multielement cemented lens systems
- Concave and convex mirrors
