Product Description
Brief Introcuction of Optical Window
Optical window is one of the basic optical elements in, used to separate the environment on both sides, such as separating the inside and outside of the instrument, so that the inside and outside of the instrument are isolated from each other, thereby protecting the internal devices.
It does not change the optical magnification and only affects the optical path in the optical path.
