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.
