N-BK7 optical blank window

--N-BK7 is a borosilicate crown optical glass, which has high homogeneity, low bubble and inclusion content. Its good physical and chemical properties make it widely used in visible and near IR range.

--N-BK7 windows plate are ideally suited for industrial applications. Available uncoated or with a MgF2 anti-reflection coating, windows are often used as a protective element between two environments.

--K9(BK7) has excellent mechanical properties and very low bubbles and impurities, with good scratch resistance.Due to its stable chemical properties, no special treatment for grinding and
polishing.

--N-bk7(k9) material has a lot of advantage in many different way,like the excellent quality,and uniform transmission in the visible,there are virtually free of bubbles and inclusions,very high  refractive index homogeneity.

Fused silica Optical blank window

--Fused silica windows has a high degree of purity,and normally they are superior enviromental durability,extremley temperature resistant ability,they have excellent transmission from UV to the NIR,exceptional hardness for demanding application which require a high degree of flatness.
--The optical quartz glass window plate produced by our factory can withstand high temperature and high pressure, mainly used in: optical instrument, optoelectronics, industry, metallurgy, semiconductor, optical communication and
other fields.

1. JGS1 (far ultraviolet quartz glass)
It has a transmittance of up to 90% at 185m. It is an excellent optical material in the 185-2500 m waveband.
2. JGS2 (ultraviolet quartz glass) It is a good material in the 220-2500 m band.

3. JGS3 (infrared quartz glass) ,It is an optical material with a high transmittance of over 85% and a band range of 260 to 3500m.
