Nrog nws cov kev ua tau zoo xws li ceev ceev, raug thiab kev nyab xeeb, laser rangefinders maj mam hloov daim kab xev ntsuas hauv ntau thiab ntau qhov chaw. Laser rangefinders, raws li lub npe qhia, siv lasers ua cov khoom tseem ceeb ua haujlwm. Tam sim no, cov ntaub ntawv ua hauj lwm ntawm cov handheld laser rangefinders ntawm kev ua lag luam feem ntau suav nrog cov hauv qab no: semiconductor lasers nrog ua haujlwm wavelengths ntawm 905 nanometers thiab 1540 nanometers, thiab YAG lasers nrog ua hauj lwm wavelengths ntawm 1064 nanometers. Lub wavelength ntawm 1064 nanometers yog teeb meem rau tib neeg cov tawv nqaij thiab ob lub qhov muag, tshwj xeeb tshaj yog yog hais tias lub qhov muag raug yuam kev ntawm lub laser ntawm 1064 nanometers, kev puas tsuaj rau lub qhov muag tej zaum yuav mus tas li. Yog li ntawd, thaum yuav lub laser rangefinder, muaj" nyab xeeb" thiab" tsis zoo" cov ntsiab lus.
