Laser rabhoritariruzivo rwekuchengetedza
Mumakore achangopfuura, nekuenderera mberi kwekusimudzira kweindasitiri ye laser,Laser tekinorojichave chikamu chisinga patsanurike chesainzi yekutsvagisa ndima, indasitiri uye hupenyu.Kune vanhu vane photoelectric vanoita muindasitiri yelaser, kuchengetedzeka kwelaser kune hukama zvakanyanya nemarabhoritari, mabhizinesi uye vanhuwo zvavo, uye kudzivirira kukuvadzwa kwelaser kune vashandisi chave chinhu chinonyanya kukosha.
A. Mwero yekuchengetedza yelaser
Kirasi1
1. Kirasi1: Simba reLaser <0.5mW.Laser yakachengeteka.
2. Kirasi1M: Hapana chakaipa mukushandiswa kwakajairika.Paunenge uchishandisa zvinotarisisa zvemaziso zvakaita seteresikopu kana magirazi madiki ekukudza, pachave nenjodzi dzinodarika muganhu weClass1.
Class2
1, Kirasi2: Laser simba ≤1mW.Kuratidzwa kwepakarepo kweasingasviki 0.25s kwakachengeteka, asi kuitarisa kwenguva yakareba kunogona kuva nengozi.
2, Class2M: chete kune ziso rakashama risingasviki 0.25s instantaneous irradiation yakachengeteka, kana kushandiswa kweteresikopu kana girazi diki rekukudza uye imwe yekuona yekuona, kuchave nekudarika kukosha kweClass2 muganho wekukuvadza.
Class3
1, Kirasi3R: Laser simba 1mW ~ 5mW.Kana ichingoonekwa kwenguva pfupi, ziso revanhu richaita imwe nzvimbo yekudzivirira mukudzivirira kuratidzwa kwechiedza, asi kana chivara chechiedza chikapinda muziso revanhu kana chakatarisa, chinokonzera kukanganisa kune ziso remunhu.
2, Kirasi3B: Laser simba 5mW ~ 500mW.Kana zvichigona kukonzera kukuvara kumaziso kana wakatarisa zvakananga kana kufungisisa, zvinowanzo chengeteka kuti utarise ratidziro yakapararira, uye zvinokurudzirwa kupfeka magirazi ekudzivirira e laser paunenge uchishandisa iyi nhanho yelaser.
Class4
Laser simba:> 500mW.Izvo zvinokuvadza kumaziso neganda, asi zvakare zvinogona kukuvadza zvinhu zviri padyo nelaser, kubatidza zvinhu zvinobvira, uye zvinoda kupfeka magogi e laser kana uchishandisa iyi nhanho yelaser.
B. Kukuvadza uye kudzivirira kwelaser pameso
Meso ndiwo anonyanya kutambudzika chikamu chenhengo yemunhu kukuvadzwa nelaser.Zvakare, iyo biological mhedzisiro yelaser inogona kuungana, kunyangwe kuratidzwa kamwe chete kusingakonzere kukuvara, asi kufumurwa kwakawanda kunogona kukonzera kukuvara, vanobatwa nekudzokororwa laser kuratidzwa paziso kazhinji havana zvichemo zviri pachena, vanongonzwa kudzikira zvishoma nezvishoma muchiratidzo.Laser chiedzainovhara ese mawavelengths kubva kune yakanyanyisa ultraviolet kusvika kure infrared.Laser ekudzivirira magirazi imhando yemagirazi akakosha anogona kudzivirira kana kuderedza laser kukuvara kweziso remunhu, uye akakosha maturusi ekutanga mune akasiyana laser kuyedza.
C. Sei kusarudza zvakarurama Laser magirazi?
1, chengetedza laser band
Sarudza kana iwe uchida kuchengetedza imwe chete wavelength kana akati wandei wavelengths kamwechete.Mazhinji laser ekudzivirira magirazi anogona kuchengetedza imwe kana akawanda wavelengths panguva imwe chete, uye akasiyana wavelength musanganiswa anogona kusarudza akasiyana laser ekudzivirira magirazi.
2, OD: optical density (laser dziviriro kukosha), T: transmittance yebhendi rekudzivirira
Laser ekudzivirira magogi anogona kukamurwa kuita OD1+ kusvika OD7+ mazinga zvinoenderana nedanho redziviriro (yakakwira iyo OD kukosha, iyo yakakwirira chengetedzo).Pakusarudza, isu tinofanirwa kutarisisa kukosha kweOD inoratidzwa pamagirazi ega ega, uye isu hatigone kutsiva zvese zvinodzivirira laser zvigadzirwa nelenzi imwe yekudzivirira.
3, VLT: inooneka mwenje transmittance (ambient mwenje)
"Visible light transmittance" inowanzova imwe yemaparamita anoregedzerwa zviri nyore pakusarudza magirazi ekudzivirira emalaser.Paunenge uchivhara iyo laser, iyo laser inodzivirira girazi inovharawo chikamu chechiedza chinooneka, ichikanganisa kutarisa.Sarudza yakakwira inooneka mwenje transmittance (yakadai seVLT> 50%) kufambisa kutarisisa kwakananga kwelaser experimental phenomena kana laser processing;Sarudza yakaderera inooneka mwenje transmittance, inokodzera chiedza chinooneka inguva dzakasimba.
Ongorora: Ziso re laser opareta harigone kunanga zvakananga kune laser beam kana mwenje waro unotaridza, kunyangwe kupfeka laser inodzivirira girazi haigone kutarisisa padanda (rakatarisana negwara re laser emission).
D. Dzimwe chenjedzo nedziviriro
Laser reflection
1, kana uchishandisa laser, vanoedza vanofanira kubvisa zvinhu zvine zvinoratidzira (senge wachi, marin'i nemabheji, nezvimwewo, zviratidziro zvine simba) kudzivirira kukuvara kunokonzerwa nechiedza chinoratidzwa.
2, laser keteni, mwenje baffle, danda muunganidzi, nezvimwe, zvinogona kudzivirira laser diffusion uye kurasika kufungisisa.Iyo laser yekuchengetedza nhovo inogona kuvhara danda relaser mukati meimwe nhanho, uye kudzora switch yelaser kuburikidza nelaser kuchengetedza nhoo kudzivirira kukuvara kwelaser.
E. Laser chinzvimbo uye kucherechedza
1, yeiyo infrared, ultraviolet laser danda risingaonekwe neziso remunhu, usafunge kuti kutadza kwelaser uye kutarisa kweziso, kutarisa, kumira uye kuongorora kunofanirwa kushandisa infrared / ultraviolet kuratidza kadhi kana chiridzwa chekutarisa.
2, yefiber yakasanganiswa kubuda kwelaser, yakabatwa neruoko fiber kuyedza, haingozokanganisa mhedzisiro yekuyedza uye kugadzikana, kuiswa kwakashata kana kukwenya kunokonzerwa nefiber displacement, laser yekubuda nzira panguva imwe chete yakachinjika, ichaunzawo huru. njodzi dzekuchengetedza kune vanoedza.Kushandiswa kwe optical fiber bracket kugadzirisa optical fiber haisi kungovandudza kugadzikana, asiwo kunovimbisa kuchengetedzwa kwekuedza kusvika pamwero mukuru.
F. Dzivisa njodzi uye kurasikirwa
1. Zvinorambidzwa kuisa zvinhu zvinopisa uye zvinoputika munzira iyo laser inopfuura.
2, simba repamusoro reiyo pulsed laser yakakwira zvakanyanya, izvo zvinogona kukonzera kukuvadzwa kune zvikamu zvekuedza.Mushure mekusimbisa kukuvara kwekupikisa chikumbaridzo chezvikamu, kuedza kunogona kudzivirira kurasikirwa kusingakoshi pachine nguva.
