Specific embodiment
In order to keep the purpose of this utility model, technical solution and advantage clearer, with reference to the accompanying drawing and it is embodied
The utility model is described in detail in example.
It please refers to shown in Fig. 2 to Fig. 5, a kind of cell slice test device 100, for the spectral response measurement of cell piece, packet
Include testboard 1, probe unit 2 and the vacuum suction pipe 3 connecting with testboard 1；Vacuum suction pipe 3 is for aspirating testboard 1
Interior air is the sample to be tested being placed on testboard 1 stabilization to be adsorbed on testboard 1.
Testboard 1 includes the support portion 11 of inner hollow and is used to place the conductive glass of sample to be tested on support portion 11
Glass 12.Electro-conductive glass 12 is to prepare the ITO that indium tin oxide films obtain in transparent glass matrix surface by magnetically controlled sputter method
Transparent conducting glass has good conductive property, reflectivity is low, translucency is good.In this way, carrying out cell piece spectral response
When test, not by cell piece absorb light can transmitted through electro-conductive glass 12, will not be reflected by electro-conductive glass 12 and be gradually resorbed and
Test value is influenced, test accuracy is improved；Compared to traditional 20 ' of gold-plated table top, production cost is reduced.
Electro-conductive glass 12 is equipped with several vacuum absorption holes 121, and vacuum absorption holes 121 are used for vacuum suction sample to be tested.
In the present embodiment, vacuum absorption holes 121 are annular in shape is uniformly distributed on electro-conductive glass 12.It should be noted that vacuum
