便携式色差仪HP-2132

概述:

    1931年, CIE(国际标准照明委员会)建立了一系列表示可见光谱的颜色空间标准。基本的CIE色空间标准是CIE_XYZ,它建立在标准观察者的视觉能力的基础上就是说它反映了标准的人眼可见颜色的范围。基于CIE_XYZ又有CIE_xyY、CIE_Lab、CIE_Lch等标准颜色空间。
目前业界最常用的是CIE_Lab色空间。CIE_Lab色空间以L值表示颜色的明度、a值表示颜色的绿红值、b值表示颜色的蓝黄值。如果单纯以一组Lab值来判断某个颜色并没有太大的实际意义,但是当我们对两个颜色进行比较时,我们可以通过这两个颜色的Lab差值来判断出它们之间的差别。
 

技术指标:

测量精度
0.20△E*ab以内

CIE色空问坐标图
 
与电脑连接进行测量分析
色差公式:
△E*=[(△L*)2+(△a*)2。+(△b*)2]1/2。
△L=L*样品-L*标准(明度差异)
△a=a*样品-a*标准(红/绿差异)
△b=b*样品-b标准(黄/蓝差异)
 
工作原理
   自动比较样板与被检品之间的颜色差异,输出CIE_Lab--三组数据和比色后的△E、△L、△a、△b四组色差数据。
△E总色差的大小:
⊙ △L+表示偏白,△L--表示偏黑
⊙ △a+表示偏红,△a--表示偏绿
⊙ △b+表示偏黄,△b--表示偏蓝
 
范围
色差(容差)
0-0.25△E
非常小或没有;理想匹配
0.25-0.5△E
微小;可接受的匹配
0.5-1.0△E
微小到中等;在一些应用中可接受
1.0-2.0△E
中等;在特定应用中可接受
2.0-4.0△E
有差距;在特定应用中可接受
4.0△E以上
非常大;在大部分应用中不可接受

 
用途概述:该仪器广泛用于塑胶、印刷、金属喷涂等行业的品质检查和监控。
