低噪聲InGaAs近紅外光譜儀
SM304是一款高分辨率、寬動(dòng)態(tài)范圍、高信噪比的高性能科研級(jí)光譜儀,采用SM304 TE cooled InGaAs陣列探測(cè)器,適用于弱光源短紅外測(cè)量。還采用TE制冷,確保了儀器長(zhǎng)時(shí)間穩(wěn)定的工作。應(yīng)用SP公司的光路和電子系統(tǒng),使暗噪聲和雜散光控制到最小。
SM304是一款高信噪比、高動(dòng)態(tài)范圍的近紅外光譜儀。采用制冷型InGaAs陣列探測(cè)器,使得SM304在需要低噪聲光譜方面的應(yīng)用具有很大的優(yōu)勢(shì)。
該光譜儀采用標(biāo)準(zhǔn)的USB 1.1/2.0數(shù)據(jù)傳輸接口,可以與計(jì)算機(jī)更友好結(jié)合。同時(shí)配置SP研發(fā)的SM32Pro操作軟件和開(kāi)發(fā)包,使用戶可以靈活控制自動(dòng)快門和進(jìn)行數(shù)據(jù)采集,不用重置探測(cè)器以消除非信號(hào)光,有利于盡心弱光信號(hào)測(cè)量。
