  • Using Laser Beam Expanders
    Laser Beam expanders are designed to decrease the laser's beam spot size at large distances. There are two main types of beam expanders: Keplerian and Galilean. In its simplest form, the Galilean type consists of a positive and a negative focal length lens whereas the Keplerian type consists of two
