Low melting point optical glass

Currently, there are about 200 kinds of colorless optical glass at the Company, including special dispersion fluorophosphate optical glass, ultra-high refractive index optical glass, high transmittance optical glass, and low melting point optical gl

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:

n_d：±50×10^-5；

υ_d：±0.5%。

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

Major application

Aspherical preforms or aspherical optical components can be prepared to be applicable to consumer electronics, industrial applications, and optical equipment, etc.
