Advantest Q8341 yog qhov ntsuas qhov muag pom pom pom hluav taws xob nrog lub wavelength ntawm 350 nm txog 1{{10}}00 nm. Vim tias nws siv Fourier spectrum system nrog Michelson interferometer, Q8341 tuaj yeem ntsuas kev sib raug zoo. Nrog nws qhov nqaim wavelength daws teeb meem ntawm 0.01 nm (nrog kev xaiv), Q8341 zoo heev rau kev ntsuam xyuas tsis yog CD/DVD laser diodes xwb, tab sis kuj rau xiav-violet laser diodes. Tsis tas li ntawd, lub built-in He-Ne laser ua raws li lub wavelength siv los xyuas kom meej lub siab wavelength ntsuas qhov tseeb ntawm ± 0.01nm (nrog kev xaiv). Thaum kawg, nrog nws ceev 0.5 s (nrog kev xaiv) ntsuas ceev, Q8341 yog qhov zoo tagnrho rau kev ntsuas qhov kub thiab txias ntawm cov khoom siv.

Kev ntsuas txoj cai

Lub Q8341 siv Michelson interferometer. Hauv qhov kev npaj no, lub teeb los ntawm cov cuab yeej-hauv-kev sim yog sib cais thiab taug kev hauv ob txoj hauv kev (nrog kev cuam tshuam ntawm ob txoj kev teeb pom kev). Los ntawm qhov no, ib qho interferogram yog tsim. Kab rov tav axis sawv cev qhov sib txawv ntawm qhov ntev (piv txwv li, lub sijhawm lossis theem) ntawm ob txoj kev teeb. Nyob rau hauv sib piv, lub ntsug axis sawv cev rau kev cuam tshuam lub teeb siv. Qhov no yog autocorrelation ntawm cov cuab yeej-hauv-test. Ua ib qho FFT ntawm qhov kev ua haujlwm no ces yields lub zog spectrum. Txhawm rau pab nrog qhov no, He-Ne laser yog siv los ua qhov siv wavelength.

Kev ntsuas ceev ceev: 0.5 s.

Zoo tagnrho rau kev tsim khoom / chaw tsim khoom

Q8341 ntsuas qhov ntsuas tag nrho hauv kwv yees. 0.5 vib nas this. Qhov no ua rau Q8341 zoo tagnrho rau laser thiab lub teeb-emitting diode ntau lawm kab. Tsis tas li ntawd, qhov kev ntsuas ceev ceev no yog qhov zoo tagnrho rau qhov chaw siab dhau los.

Zoo heev coherence tsom xam ntev

Analysis ntev: Approx. 40mm, MAX (xaiv)

Kwv yees li. 10 hli, MAX (standard)

Max. kev daws teeb meem ntev: 0.001 mm

Q8341 kuj ntsuas lub laser diode txoj kev sib koom ua ke rau optical discs. Nrog rau kev soj ntsuam ntev ntev txog li 40 hli thiab qhov kev daws teeb meem nqaim ntawm 0.001 hli, Q8341 yog qhov zoo tshaj plaws rau kev ntsuas xiav-violet laser diodes thiab lwm cov khoom siv kho qhov muag.

High wavelength raug

Qhov tseeb wavelength: ±{{0}}.01 nm (xaiv), ± 0.05 nm (tus qauv)

Nrog nws cov built-in Ne-He laser siv lub teeb qhov chaw, Q8341 ntsuas spectrum nrog siab wavelength raug.

Nqaim-kev daws teeb meem los ntsuas qhov oscillation hom ntawm xiav-violet laser diodes

Wavelength daws teeb meem (ntawm 650 nm): 0.01 nm (xaiv), 0.05 nm (tus qauv)

Nrog nws txoj kev daws teeb meem nqaim, Q8341 cais cov oscillation hom ntawm xiav-violet laser diodes. Tsis tas li ntawd, qhov ntsuas kev daws teeb meem ntawm lub ncov wavelength ntawm 0.001 nm yog qhov zoo tagnrho rau kev soj ntsuam ntsuas qhov tshwm sim cuam tshuam los ntawm ib puag ncig ib puag ncig ntawm DUT.

Rau high-throughput ntsuas

Ua haujlwm lub cim xeeb muaj peev xwm loj thiab kev ua haujlwm siab, Q8341 khaws cov ntaub ntawv sai. Cov ntaub ntawv no yog xam los ntawm chav tsev los qhia txog qhov teev wavelength thiab ncua. Piv txwv li, yog tias Q8341 soj ntsuam cov spectrums ntawm ob lub wavelength ranges (650 nm ± 50 nm thiab 780 nm ± 50 nm), nws ua tiav cov spectrum tsom xam ntawm 2 cais LDs los ntawm kev hloov tsuas yog nws cov zaub ntau yam. Tag nrho cov no yog ua tsis tau reconfigure lub system. Li no, Q8341 txo lub sijhawm ntsuas rau kev siv ntau lawm.

Kev ntsuas piv txwv

Coherent ntsuas ntawm DVD laser diode

Ib qho tseem ceeb coherence yam ntxwv ntawm DVD laser diodes yog txiav txim siab qhov cuam tshuam piv cov zis ntawm lub ncov mus rau lub ncov thib 2. Q8341 ntsuas qhov no los ntawm kev nias tus yuam sij. Nws kuj tseem qhia txog cov kev sib koom ua ke raws li cov ntaub ntawv tshwm sim.

Tsis siv neeg ntsuas: Peak wavelength, nruab nrab wavelength thiab spectral dav ntawm laser diodes

Lub ncov wavelength (λp), nruab nrab wavelength (λo) thiab spectral dav (Δλ) yog qhov tseem ceeb spectrum ntsuas ntsuas rau laser diodes. Nrog ib tus yuam sij, Q8341 cia li xam thiab qhia cov txiaj ntsig ntawm CRT.

Dav dynamic ntau yam

Nrog kev xaiv 70, Q8341 ua kev ntsuas nrog nqaim daws teeb meem. Qhov no ua rau koj cais cov oscillation hom rau 405 nm band LDs.
