K9 optical Dome
PRODUCT CATEGORIES
Dome window is a protective window with hemispherical shell shape. It is often used in the application of incident light in large angle range, such as detector, optical sensor and so on.
BK7 (K9) Dome window can be seen from the transmittance of near-infrared (350-2000nm). It is a common optical glass for preparing optical elements. When the additional advantages of UV fused quartz (good transmittance and low coefficient of thermal expansion in UV band) are not required, H-K9L will generally be selected.
