Low-Softening-Point Optical Glass
Low-softening-point optical glass is environmentally friendly optical glass with a softening temperature generally below 600°C. It is suited to precision molding: the lower forming temperature helps shorten forming time and extend mold service life. The company offers more than 20 types, mainly used to make aspheric preforms and aspheric optical components.
