商品说明折射指数或阿贝数( vd 或 ve ) 可依据450 至 1,100nm范围内的不同波长来衡量。DR-M2能在液晶屏幕上数字显示折射指数与阿贝数。 Refractive index or Abbe number ( νd or νe ) can be measured at different wavelengths ranging from 450 to 1,100nm.The DR-M2 digitally displays measurement result of refractive index or Abbe number on the LCD.Measurement can be achieved by matching the boundary line with the intersection point of the cross hairs.This refractometer is connectable with Digital printer DP-21 ( A ) ( Optional ) .ModelDR-M2型号1410测量范围折射指数 1.3277 至 1.7379 ( 波长450nm )折射指数 1.3000 至 1.7100 ( 波长589nm )折射指数 1.2912 至 1.7011 ( 波长680nm )折射指数 1.2746 至 1.6843 ( 波长1,100nm )最小显示单位折射指数 : 0.0001阿贝数 : 0.1测量准确度折射指数 : ±0.0002( 附589nm 测试片 )波长范围从 450 至 1100nm ( 具滤波干扰器)( 对于681 至 1100nm的波长，则需要近红外线观察器（可选购）)温度测量范围5 至 50°C输出终端机数字打印机 DP-21 (A) (选件)电源AC100 至 240V 50/60Hz电力损耗100VA尺寸重量13×29×31公分, 6.0千克 (折射仪)15×33×11公分, 3.0千克 (光源组件)选件• 胶卷测量用采光玻璃片 (DR-M2用) : RE-6191• 数字打印机 DP-21 (A) : 型号 3011• 干涉滤光589(D)nm : RE-3520486(F)nm : RE-3521656(C)nm : RE-3522546(e)nm : RE-3523480(F')nm : RE-3524644(C')nm : RE-3525(选择波长) : RE-3526450 至 539nm540 至 680nm681 至 799nm800 至 1110nm• 近红外线透镜 : RE-9119• 带偏光板接眼镜 : RE-1146消耗品/零件• 刻度校正用 A : RE-1195• DR-M2用主副菱镜 : RE-1600• 光源灯泡 DR-M2, M4 : RE-4170• 干燥剂 : RE-1592ModelDR-M2Cat.No.1410Measurement RangeRefractive index 1.3277 to 1.7379 ( Wavelength 450nm )Refractive index 1.3000 to 1.7100 ( Wavelength 589nm )Refractive index 1.2912 to 1.7011 ( Wavelength 680nm )Refractive index 1.2746 to 1.6843 ( Wavelength 1,100nm )Minimum IndicationRefractive index : 0.0001Abbe number : 0.1Measurement AccuracyRefractive index : ±0.0002( With the attached test piece at 589nm )Wavelength RangeFrom 450 to 1100nm ( with interference filters )( For measurement at wavelengths ranging from 681 to 1100nm, the Near Infrared Ray Viewer ( Optional ) is required )MeasurementTemperature Range5 to 50°COutput TerminalFor printer, DP-21 (A) (Optional)Power SupplyAC100 to 240V 50/60HzPower Consumption100VADimensions & Weight13×29×31cm, 6.0kg (Refractometer)15×33×11cm, 3.0kg (Light source unit)Optional•Lighting glass for film measuerment (for DR-M2) : RE-6191•Digital printerDP-21 (A) : Cat.No.3011• Interference filter589(D)nm : RE-3520486(F)nm : RE-3521656(C)nm : RE-3522546(e)nm : RE-3523480(F')nm : RE-3524644(C')nm : RE-3525(select one wavelength) : RE-3526450 to 539nm540 to 680nm681 to 799nm800 to 1110nm• Near-infrared ray viewer : RE-9119•Eyepiece for polarizing : RE-1146Parts•Test piece A with m-naphthalene : RE-1195•Main & secondary prism for DR-M2 : RE-1600•Illuminating lamp for DR-M2, M4 : RE-4170•Pack of desiccant tablets : RE-1592产品技术参数技术指标测量范围折射指数 1.3277 至 1.7379 ( 波长450nm )；折射指数 1.3000 至 1.7100 ( 波长589nm )；折射指数 1.2912 至 1.7011 ( 波长680nm )；折射指数 1.2746 至 1.6843 ( 波长1,100nm )分辨率折射指数 : 0.0001 阿贝数 : 0.1测量精度折射指数 : ±0.0002( 附589nm 测试片 )使用温度范围5 至 50°C480(F')nmRE-3524(选择波长)RE-3526644(C')nmRE-3525589(D)nmRE-3520546(e)nmRE-3523656(C)nmRE-3522选件：胶卷测量用采光玻璃片 (DR-M2用)RE-6191；数字打印机 DP-21 (A)消耗品/零件： 刻度校正用 ARE-1195；DR-M2用主副菱镜近红外线透镜RE-9119；带偏光板接眼镜486(F)nmRE-3521物理特性尺寸13×29×31公分(折射仪) 15×33×11公分(光源组件)重量6.0千克 (折射仪) 3.0千克 (光源组件)电源AC100 至 240V 50/60Hz
