With the improvement of people's consumption level, a variety of convenient devices have emerged, and barcode scanners are a typical example. When we shop in supermarkets, we often see salespersons using Supermarket Desktop Barcode Scanner to scan products. The function of the barcode scanner is to convert the data in the barcode into computer language and perform statistics and payment settlement. Friends who are related to the barcode scanning industry or who have known it know that if you want to classify barcode scanner according to optical types, they can be divided into "laser" and "red light". So what is the difference between these two types of barcode scanners? The following is a brief introduction by the editor of Honor Way electronics.
1. Qhov txawv ntawm txoj cai
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub laser barcode scanner yog tias lub teeb pom kev ntawm lub teeb yog tsim los ntawm cov khoom siv laser sab hauv, ntaus ib daim ntawv qhia nrog cov cuab yeej siv tshuab, thiab tom qab ntawd tso siab rau qhov kev vibration ntawm lub vibration lub cev muaj zog kom viav vias laser taw tes rau hauv ib qho khoom siv hluav taws xob. laser kab kom ci rau ntawm barcode, thiab ces hla dhau. AD tau txiav txim siab rau hauv lub teeb liab digital. Lub teeb liab Embedded QR Code Reader feem ntau siv LED teeb -emitting diode lub teeb qhov chaw, cia siab rau CCD photosensitive element, thiab ces hloov dua siab tshiab los ntawm photoelectric teeb liab.
2. Qhov sib txawv ntawm kev poob kuj yog qhov loj
Feem ntau cov laser barcode scanners cia siab rau cov kua nplaum los kho cov cuab yeej siv tshuab, yog li nws feem ntau yooj yim puas thaum nws viav vias. Yog tias lub viav vias ntog tawm, peb feem ntau tuaj yeem pom tias lub teeb pom kev los ntawm qee lub laser scanners tom qab ntog dhau los ua qhov taw tes, ua rau muaj kev ua haujlwm siab heev. Lub teeb liab Embedded QR Code Reader tsis muaj cov qauv siv tshuab hauv nruab nrab thiab muaj kev ruaj ntseg zoo, yog li qhov kev poob siab muaj zog ntau dua li ntawm laser scanner. Hais txog cov ntaub ntawv piv txwv, lub teeb liab 2D Barcode Reader Module kho tus nqi qis dua li ntawm lub laser scanning module.
3. Qhov txawv ntawm lub cev lub hauv paus ntsiab lus ntawm lub teeb
Los ntawm qhov kev xav ntawm lub cev lub hauv paus ntsiab lus ntawm laser thiab lub teeb liab, laser hais txog lub teeb nrog lub zog txhawb zog hluav taws xob thiab zoo parallelism, uas yog lub teeb ntawm ib co wavelength; thiab tam sim no feem ntau ntawm lub teeb liab yog tawm los ntawm LED, uas yog lub teeb yoj pom ntawm qhov muag liab qab. Lub teeb liab tsis yog qhov peb hu ua lub teeb infrared. Infrared, raws li txhais los ntawm physics, yog ib tug electromagnetic nthwv dej radiated spontaneously los ntawm cov khoom nrog kub, uas yog tsis pom. Los ntawm lub wavelength thiab lub zog ntawm laser thiab lub teeb liab, kev nkag mus thiab tiv thaiv - cuam tshuam ntawm lub teeb liab yog qhov phem tshaj ntawm laser nyob rau hauv lub teeb muaj zog, thiab lub laser zoo dua lub teeb liab nyob rau hauv lub teeb muaj zog sab nraum zoov.
Well, according to the above three points, you can simply understand the difference between laser and red light. If there is anything you don't understand, please feel free to consult us.
