Half-Spherical Lens |
|
 |
A hemispherical lens is a convex lens that does not have a side called
an edge, unlike a normal lens. This lens has a positive focal length and
is used for image magnification and light collection applications.
It is used for the tip of high-magnification objective lenses, etc., because
it increases the efficiency of light incident on the lens surface from
the object.
The product shown is uncoated.
