簡(jiǎn)介:
SpectraPen LM510手持式光譜儀是目前功能最為全面的多用途手持式光譜儀。它不但可以測(cè)量光譜特征曲線(xiàn),同時(shí)計(jì)算用戶(hù)指定波段的Lux(勒克斯)、Lumen(流明)、PAR(光合有效輻射)和Watt(瓦特)值,用于在實(shí)驗(yàn)室、溫室或野外進(jìn)行光強(qiáng)、光質(zhì)和光譜圖測(cè)量。它還可以應(yīng)用于環(huán)境、農(nóng)業(yè)和生態(tài)學(xué)研究,比如人造光源測(cè)試、自然光監(jiān)測(cè)等。
SpectraPen LM510通過(guò)觸控屏進(jìn)行操作,配備余弦校正頭和內(nèi)置GPS,由可充電鋰電池供電。光譜圖和所有計(jì)算數(shù)據(jù)都能夠?qū)崟r(shí)顯示并自動(dòng)存儲(chǔ)到儀器內(nèi)存中。通過(guò)專(zhuān)用軟件包可將數(shù)據(jù)下載到電腦中并進(jìn)行數(shù)據(jù)前處理。

儀器型號(hào):
SpectraPen LM500有以下4種型號(hào):
UVIS表示測(cè)量波長(zhǎng)范圍為340-780nm(紫外-可見(jiàn)光區(qū))
NIR表示測(cè)量波長(zhǎng)范圍為640-1050nm(近紅外區(qū))
H表示余弦校正器向上,用于較小空間(如培養(yǎng)箱內(nèi))測(cè)量,也可用于野外測(cè)量
V表示余弦校正器向前,用于野外測(cè)量,可配合三腳架進(jìn)行測(cè)量
三腳架(選配,只能用于V型)
