Excellent transmission properties from near ultraviolet to near infrared, suitable for a wide range of applications including high temperature and high pressure environments.
■Synthetic quartz
Synthetic quartz is an optical glass material for transmission, but because it has a much lower expansion than materials such as BK7, it is used as a high-precision substrate for various optical products.
■Features
・The transmittance in the visible and ultraviolet regions is the highest among optical glasses, and there are few bubbles and impurities.
・Low thermal expansion, wide usable temperature range (maximum temperature around 800℃)
・Low fluorescence even under strong ultraviolet light.
・The material is harder than other materials and is less prone to scratches.
