Micro Preform Lens is a glass material that is precisely manufactured
from optical glass. Having highly precise dimensions and
small surface roughness, it is used as a preform glass material
for glass aspherical lens in optical pick-ups for DVD, MD
and MO, etc. It is also used in cameras, such as video cameras,
digital still cameras, and so on. Its spherical shape makes
it very easy to load into the mold.
