Product information

The low melting point environment friendly glass used for moding and forming are applicable to precision 

molding and forming, with comparatively lower glass forming temperature, which is conducive to shorten forming duration, and to prolong service life of molds.

Form of supply
Technical information

The data of low melting point optical glass after annealed at -30 ℃/h, which is different from nd and ud of glass in the final practical application.

The cooling rate in the precision molding process is high, so the nd of products after precision molding is lower than the nd based on annealing at -30℃/h as provided on the certificate of quality. The reduction degree of nd depends on glass brands, precision molding process and geometric shapes of products, etc.

The difference between the refractive index nd and Abbe number of each batch of products ud from the standard value is generally within the following tolerance range:

折射率nd:±50×10-5;

阿贝数υd:±0.5%。

If there is any special requirement, the Company may adjust the nd and ud of glass approximately as required by customers.
