美國D&S公司 15R-RGB 便攜式鏡面反射率計是 15R-USB便攜式鏡面反射率計 的升級版。
美國D&S公司 15R-RGB 便攜式鏡面反射率計技術(shù)參數(shù)如下
USB: A USB port is provided for maintaining and downloading data sets and upgrading the firmware.
LIGHT SOURCE: High intensity white light emitting diode (400-800 nm). This source is chopped at 90 Hz, eliminating stray light problems.
OPTICS: The LED source is mounted behind a small aperture which provides a near point source. This is collimated into a beam by a converging lens. An identical lens focuses the reflected beam into the collection aperture.
FILTER SELECTION: Broad band red, green, blue and IR filters selected via a filter wheel. One additional filter position is unfiltered for measurement over the full spectrum of the white LED.
APERTURE SELECTION: Five apertures providing 4.6, 7, 15, 25 and 46 milliradian full acceptance angles.
ALIGNMENT SYSTEM: Three threaded supports provide for adjustment to bring the reflected beam into alignment with the receiving optics and to compensate for different thicknesses of second surface reflectors.
CALIBRATION STANDARD: A working standard is mounted in a protective housing that couples into the base of the instrument.
RESOLUTION: A 3 ? digit LCD display indicates reflectance directly to 0.1%. A gain adjust knob allows the user to calibrate the instrument with the working standard.
REPEATABILITY: +/- 0.002 reflectance units.
OPERATING TEMPERATURE: 32 to 122 F (0 to 50 C).

美國D&S公司15R-RGB 便攜式鏡面反射率計介紹:
便攜式鏡面反射率計采用可充電電池供電,每次充電完成后可連續(xù)測量15個小時。反射計設(shè)計小巧,高約15cm,直徑12.7cm,重量1.0kg,測量時間約每分鐘2~6次并自動記錄和存儲數(shù)據(jù)。具有USB接口可進(jìn)行數(shù)據(jù)下載、數(shù)據(jù)維護(hù)和固件升級。這些特點對于現(xiàn)場太陽反射鏡的測量、檢測、生產(chǎn)過程中的質(zhì)量控制、熱控制涂層的維護(hù)等應(yīng)用領(lǐng)域非常理想。
具有如下優(yōu)點:
(1)電池操作,野外便攜
(2)重復(fù)性:±0.002
(3)質(zhì)量控制和檢測的理想應(yīng)用產(chǎn)品

美國D&S公司15R-RGB 便攜式鏡面反射率計原理介紹:
美國D&S公司 15R-RGB 便攜式鏡面反射率計使用660nm的LED光源,通過校準(zhǔn)光學(xué)部件產(chǎn)生10mm直徑光束源。反射的光束穿過3個孔中的1個,標(biāo)準(zhǔn)接收角度為15、25和46mrad,提供7mrad可選孔徑。15R-USB基座上有兩個可調(diào)節(jié)的支承點,可用來調(diào)準(zhǔn)反射光束與接收光學(xué)系統(tǒng)。
支撐點中間具有停止位,可以根據(jù)反射鏡厚度來調(diào)節(jié);為了確認(rèn)對準(zhǔn),可旋轉(zhuǎn)檢測器,通過美國D&S公司 15R-RGB 便攜式鏡面反射率計頂部的目鏡查看光學(xué)路徑和反射光束。LED光源通過電子截光并同步測量反射光束以消除雜散光誤差。同時,光源通過參比檢測器監(jiān)測以減少熱漂移。增益調(diào)節(jié)可將測量值**到0.001。在儀器的底部,提供一個封裝的標(biāo)準(zhǔn)體。
測量反射率時,只需將美國D&S公司 15R-RGB 便攜式鏡面反射率計置于待測量的反射鏡上,并調(diào)節(jié)支撐點到液晶屏顯示的*大讀數(shù)。
- 溫馨提示:為規(guī)避購買風(fēng)險,建議您在購買前務(wù)必確認(rèn)供應(yīng)商資質(zhì)與產(chǎn)品質(zhì)量。
