Lenses as singlets, doublets and triplets in different shapesSpherical lenses are used in many different applications to collect, focus and diverge light. They are often components of lens systems that perform an achromatic function.
Achromatics consist of two or three elements of different lenses cemented together to limit the effect of spherical and chromatic aberration.
Spherical optics produtcs:
- Lenses plano-convex/plano-concave
- Lenses bi-convex/bi-concave
- Achromatic doublets or triplets
- Meniscus lenses
