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.

Features Small surface roughness Precise dimension of diameter permits control of weight. Diameter of lens is available upon request.
