K9 Wedge Windows

K9 glass wedge angle pieces have characteristics such as high transmittance, high hardness, and high stability. They are used as protective windows for electronic sensors or external environmental detectors, and can change the deflection path of light. K9 glass wedge angle pieces have high transmittance and low impurity content, which can ensure that the magnification of the system will not change. It can be coated with reflective film, anti reflective film, filter film, spectroscopic film, polarizing film, and metallization film systems.
