Astronomical telescope manufacturers today are bringing astronomical telescope optical lenses to attention.

If you contact optical lens lens directly with hand, it will cause imprinting on optical lens. If long time does not wipe, it may become permanent spot print, affecting the quality of optical element imaging.

Two. Light and light, a lot of lenses are glass products, astronomical telescope lenses are no exception, easy to bump, edge, scratch, to take the edge of the lens, do not direct contact with the light surface, even if wearing a finger can not directly contact.

Three. If you don't use it, put it on the surface of a soft object. You can't directly put the bare pieces on the glass, metal, desktop or unclean paper, so that the lens is very easy to scratch.

Four. If there is a dust on the surface of the lens, blow the dust with a clean ear ball.

Five. If there are stains or sweat stains, wipe them gently with alcohol or acetone.

Six. In storage, we should pack with clean capacitor paper or mirror paper, which should be placed in a dry cabinet with moderate temperature (about 23 C) and humidity (less than 40%).

Seven. Optical lenses should not be stacked together. Each lens should not overlap.

Eight. Once it is found dirty, wash immediately, but pay attention to prevent scratches. Dust can easily scratch the lenses.
