哪里可以买到测消光比的仪器

应该可以测试到40dB
有兴趣讨论讨论。lzc@oelandau.com

UGA VPMM-100消光比测试仪(偏振分析仪) Polarization Multimeter: VPMM-100 Series 760nm-1550nm 80uW-1.5W Ratio 0-30dB Amplitude -30-+30dB res0.1dB Angle -90-+90deg Phase0-180deg res0.5deg Display8.4Hz ，Input FC fiber Head 52*115*90 1Kg Main 210*100*240 3Kg AC100V manual 1  Conventionally a special optical system and calculating process are required to measure extinction ratio and phase difference. However, with this instrument, extinction ratio and phase difference can be simply evaluated in real time. 1、Extinction ratio, Azimuth, Phase difference and Amplitude ratio can be evaluated.
2、VPMM-100 can be used with inputs of either FC connector fiber or space-collimating light.  
3、SC connector is optional.  
4、Evaluation can be performed with low level of light-input between 80uW to 1.5mW.  
5、For evaluation of Azimuth, VPMM-100 has an angle compensation function and evaluation is realized at any desired angle.  
6、Featuring a 7-step LED level for input light power  
7、Featuring Averaging function "AVE" (average over 8-times data acquired), stable evaluation with high repeatability is realized.  
8、Compact and convenient at narrow space.  
9、RS232C interface enables communication with external equipment

找上海瀚宇就可以了,服务好技术到家

消光比需要仪器吗?我们公司买入的片子测消光比都是自己动手的,用个偏振就行了。

站内帖子光通讯测试设备就有提供

现在的光学示波器就可以。

当然是安捷伦和泰克的了。
