Colorless Borosilicate Optical Quality Glass High Temperature Resistance

Round and Square Shape High Clean Temperature Resistance Borosilicate Optical Glass for Home Appliance Parts

Product description:


Borosilicate glass is one of transparent colorless glasses, the wavelength is between 350nm to 2500nm, and the transimitance is more than 90%, the high temperature is up to 400°C,If course handling, the high temperature resiatant can reach 550°C.


1. Raw material: Borosilicate glass, Pyrex, Optical glass.

2. Processing: by Molding, Grinding, Polishing.

3. Surface quality: optical surface quality and well controlled tolerance

4. Inside quality: clear and transparent, no mold marks, no inside bubble and dirts.

5. Great heat resistance performance,stable chemical property.

6. Working field :widely used in high-temperature observation windows, lighting (high-power lighting panel), appliances, laboratory containers, solar, lighting and other fields.


AUTC Optical produces of high borosilicate glass, with a good appearance, high temperature, resistance strong pressure, acid and alkali, high transparency, good quality, After cutting, grinding, polishing, milling,Tempered and so on process to complete.
