Kev nyab xeeb siv laser rangefinders
Thaum peb siv lub rangefinder los ntsuas qhov deb, tshwj xeeb tshaj yog thaum siv lub laser rangefinder, cov lus ceeb toom tshaj plaws uas peb pom yog "Tsis txhob taw tes rau qhov rangefinder ntawm lub qhov muag lossis tib neeg lub cev rau irradiation!" Txawm li cas los xij, lub laser rangefinder Qhov twg yog lub hauv paus rau kev siv "kev nyab xeeb" thiab "tsis zoo" los ntawm? Niaj hnub no, cia peb saib qee qhov kev ceev faj kom xyuam xim thaum siv lub rangefinder.
Tam sim no, lub tes tuav laser rangefinders uas tuaj yeem yuav hauv khw tuaj yeem raug faib ua: semiconductor lasers nrog ua haujlwm wavelengths ntawm 905 nm thiab 1540 nm thiab YAG lasers nrog ua haujlwm wavelengths ntawm 1064 nm. Thiab qhov peb hais txhua hnub "tsis txhob taw tes rau qhov rangefinder ntawm lub qhov muag lossis tib neeg lub cev rau irradiation" feem ntau yog hais txog lub laser nrog kev ua haujlwm wavelength ntawm 1064 nanometers. Lub laser nrog lub wavelength ntawm 1064 nanometers muaj qee yam kev puas tsuaj rau daim tawv nqaij thiab qhov muag ntawm tib neeg lub cev. Tshwj xeeb tshaj yog rau lub qhov muag, yog tias koj yuam kev tuaj rau hauv kev sib cuag nrog 1064 nanometer wavelength laser, qhov kev puas tsuaj rau lub qhov muag yog mus tas li. Xws li lasers tuaj yeem tsom mus rau retina los ntawm tib neeg lub qhov muag, thiab retina yuav raug puas tsuaj rau qee yam tom qab irradiated. Cov mob hnyav tuaj yeem ua rau lub qhov muag burnout. Lub semiconductor lasers nrog kev ua haujlwm wavelengths ntawm 905 nanometers thiab 1540 nanometers tsis tsom los ntawm tib neeg lub qhov muag. Yog li ntawd, feem ntau ntawm cov handheld laser rangefinders nrog ib tug ua hauj lwm wavelength ntawm 1064 nm nyob rau hauv txawv teb chaws lub teb chaws tau raug tshem tawm, thaum ib co domestic manufacturers tseem ua xws li rangefinders.
Thaum siv lub rangefinder los ntsuas qhov kev ncua deb ntawm ib yam khoom, nws yuav tsum tau ntsuas nyob rau hauv nruj raws li kev nyab xeeb kev ua hauj lwm specifications nyob rau hauv lub ntsuas ntsuas. Tshwj xeeb tshaj yog nyob rau hauv cov qus, peb feem ntau siv pulsed laser rangefinders, tab sis pulsed laser beams yog heev concentrated nyob rau hauv lub zog. Monochromatic teeb pom kev zoo, tsis txhob saib ncaj qha rau ntawm qhov chaw nres nkoj laser emission thaum siv nws kom tsis txhob muaj kev puas tsuaj. Txhawm rau kom ntseeg tau tias kev siv ib txwm siv ntawm cov khoom siv photosensitive ntawm lub laser rangefinder, tsis txhob tsom lub laser emission chaw nres nkoj ntawm lub hnub thaum ntsuas qhov deb hauv thaj teb.
