TIP Holder
Triaxial & coaxial/Screw,Spring & tubular type
|
Definition:
|
The tip holder is the mechanism between the micropositioner & the probing tip. As the people know it is the mechanism for holding the prbing tip.As a result, the tip and tip holder will be driven at the same time by the the micropositioner X-Y-Z knobs. |

Types :
|
1.Mechanism Aspact | |
|
a.Screw-typed:
|
Use the tiny screw in a threaded hole to
hold the probing tip which is located 45 degree.It is simplest and
cheapest. You can choose regular,coaxial & triaxial |
|
|
b.Spring-typed:
|
Use the loaded spring to hold the probing
tip.When you hold the spring-loaded pusher back,the tip hole will
appear. When you release the spring-loaded pusher,the pusher will push to hold the tip itself.You can choose regular,coaxial & triaxial. |
|
|
c.Tubular type:
|
Use the copper tube to hold the probing
tip and again use the copper tube to make the electrical shielding.There
is the insulation tube put in the between the tip holding tube and
shielding tube. You can choose coaxial & triaxial.It is not recommended
to use on the micropositioner EB-700. |
|
| 2.Electrical Aspact | ||
| a. Regular Tip holder: | The electrical signal from the tip go all
the way the tip holder body.Then the signal go thru the PVC cable.
This can measure the current level around the mA. This current level
is typical for LED,LD,PD ,OLED and some LCD. You can choose screw,spring
and tubular types. |
|
| b.Coaxial Tip Holder: | It comes with a coaxial cable 1.2 meter
long terminated with BNC male(also called coaxial male).This can measure the current level less than 10 pA with qualified shielding box. You can choose screw,spring and tubular types. |
|
| c.Triaxial Tip Holder: | It comes with a triaxial cable 1.2 meter
long terminated with triaxial male. This can measure the current level
less than 100 fA with qualified shielding box. You can choose screw,spring
and tubular types. |

Ordering:
|
Please specify the micropositioner model
number according to the resolution you need to probe onto the target.Then choose the tip holder according to the electrical aspact -coaxial or triaxial.Finally,choose the tip holder according to the mechanism aspact- screw,spring or tubular types. Make sure to consider the usage limitation for each micropositioner. |
