查询词典 lens

To make picture clear, the electron beam that must come out to be being hit from electron gun undertakes focusing is handled, let electron beam pass electron lens, be opposite with optical lens of beam of light collect action likeness, the electron beam assemble that opens scattering rises, get on fluorescent screen one shines again small spot, add the effect of scanning circuit, ability shows clear picture.
