About This Product
It has a very high purity and the impurities are small. It has excellent heat resistance and thermal impact, and has excellent light transmittance in a wide range of wavelength areas from far -infrared to near -infrared. It is used for optical products, bactericidal lamps, semiconductors, etc.
The quartz glass plate has no predetermined thick boards like a soda glass plate or a tempax glass plate, and the quartz block -shaped object is carefully polished by the skilled quartz and finished it into the desired thickness plate. I am.
Therefore, all quartz glass plates are made to order and requires about 20 days delivery. There are several materials (grade * SG, UV, ES) on the quartz glass board. Depends on the size, thickness, and order.
■ Type
・ SG material: The most common molten quartz glass is used for peeking windows of industrial furnace.
・ UV material: It is used for optical cells with molten quartz glass improved for optical use.
・ ES material: Ultra -high -purity synthetic quartz glass has excellent UV transmittance and is used for prisms and lenses.
■ Couporal difference
Size ± 0.1 to 0.3mm thickness ± 0.05mm surface accuracy 4 to 10λ
