ʻO Dot matrix kahi ʻano o ka hoʻokuʻu ʻana i ka laser.ʻO ka MED-870+ lattice laser instrument i hoʻolako ʻia me kahi mea hana kiʻi kūikawā (CPG).Hoʻololi ka mea hana kiʻi i ke ʻano hoʻokuʻu o ka mālamalama.Hiki ke hoʻokuʻu ʻia ka laser lattice ma o ke aniani nānā kiʻekiʻe.50μm-80μm kiko kiko, a nānā i kēia mau kiko kikoʻī a hiki i 6 ʻano o nā ʻano like ʻole (ka pōʻai, square, rectangle, daimana, triangle, laina), i kūpono no ka mālama ʻana i nā ʻāpana like ʻole a me nā ʻano ʻili like ʻole.
