Molded Blanks

A molded blank is a blank whose basic surface curves are attained by heating and forming a given weight of raw glass; a rough glass blank resembling the finished lens in size and shape. After molding, a precision lens blank must be fine-annealed to eliminate strain and to restore the refractive index to its stable maximum value.

Glossary
  • molded lens A lens with one or both sides fire-polished to its final surface. Lenses for condensers and viewfinders often are made in this way, an aspheric surface being as easy to mold as a sphere.
  • molded blank A blank whose basic surface curves are attained by heating and forming a given weight of raw glass; a rough glass blank resembling the finished lens in size and shape. After molding, a precision lens blank must be fine-annealed to eliminate strain...
  • optical blank A casting consisting of an optical material molded into the desired geometry for grinding, polishing or, in the case of optical waveguides, drawing to the final optical-mechanical specifications.
