Our beamsplitter plates can be used in high power laser system. When using beamsplitter plates, it is important to make it in mind that the two partial beams travel in different optical paths. The optical paths depend on the incident angle and the thickness of plates.
The Positive Meniscus
Lenses are a convex-concave lens, but it is thicker at the center than
at the edges. They are felt polished and are used universally in the
ophthalmic industry where convention dictates that lens power be
specified in Diopters.
The Negative Meniscus Lenses are a convex-concave lens, but it is
thinner at the center than at the edges. Otherwise description is
similar to Plano Concave lenses.
