Day night 850 filter with AR coating test plot

Advantage

You will get higher transmission in visible wavelength and IR wavelength if you choose GDN-850A1 in stead of GDN-850.The part GDN-850A1 is coating with AR coating on one side,but GDN-850 doesn’t have this coating.Pls check the above test curves and compare the different details.
