LPSR300 便攜式光譜反射測試儀 （近紅外）
|
LPSR 即Laboratory Portable SpectroReflectometer，獨特的采用積分球設計對大部分的材料表面進行半球光譜反射率快速測定，光譜范圍250 to 2800 nm 。主要根據(jù)ASTM E903 規(guī)范，對太陽吸收進行測定 .可同時提供用于真空環(huán)境測試版本 LPSR 300V.
LPSR 300 采用Windows XP 操作系統(tǒng)傻瓜式圖形操作界面。自動操作模式可以選擇波長起止范圍，步進間距。結果顯示為不同波長的反射率值，并自動計算太陽吸收。手動模式可選擇光源、探測器、狹縫寬度及增益。
LPSR 300 是一個獨立的測試系統(tǒng)，無需其它硬件。系統(tǒng)提供外接顯示器和鍵盤接口。內(nèi)置硬盤可存儲幾千次樣品掃描測試結果，非常適合野外和實驗室環(huán)境使用。
LPSR300 同時系統(tǒng)集成了光學數(shù)據(jù)庫，可以和測試的結果進行比對。

LPSR是根據(jù)NASA需求設計研制，用于俄羅斯MIR空間站太空行走
