Hello Grumpy_Mike,
Thank you for helping. I took a picture to help illustrate what I mean when I say lens. I realise that I am mostly likely using the wrong terminology when I say lens. The lens is the part of the object that will raise when a voltage is applied across it.
A picture would help explain what I am trying to do. I will be soldering wires to the metal pins instead of using gator clips. This is the picture of the lens.

I hooked applied a voltage across the object, so the lens in the middle will raise to the top. I found that the voltage needed to raise it to the top is 2.6V and the current drawn is 0.46 as illustrated in the circuit below:
I hope to be able to to apply a voltage that is between 0V and 2.6V, so I can keep it between its resting point and the topmost point. Thank you for spending time and effort to help me.
