Ohara's Low Softening Temperature Optical Glasses
have almost same optical constants (refractive indices and
dispersions) as conventional optical glasses and can be formed in
relatively lower temperature. This property helps to extend
the life span of pressing molds because the lower pressing
temperature saves the reaction between glass and the pressing mold.
In addition, the glasses
do not contain PbO and As2 O3 for the purpose
of environmental measure. It makes our procedures for waste
disposal much easier. Furthermore, the Low Softening
Temperature Optical Glasses are quite suitable as materials for
precision glass molding since they have almost the same general
properties as regular optical glasses such as chemical durability.
The Glass Types of
Low Softening Temperature Optical Glasses are headed with “L-“
