Unable to disable a C# script with a JS Script

I can't seem to disable "DepthOfField.cs" with my "Bino.js" script, this is the code used: #pragma strict

 var zoom : int = 20;
 var glassesVision : int = 80;
 var normal : int = 90;
 var smooth : float = 5;
 
 private var isZoomed = false;
 
 //Glasses functions
 var GlassesImageOn = false;
 var GlassesImage : GameObject;
 
 var dof : DepthOfField;
  
 function Start () {
     GlassesImage.SetActive (false);
     dof = gameObject.GetComponent("DepthOfField");
 }
 
 function Update () 
 {
     if(Input.GetMouseButtonDown(2))
     {
         isZoomed = !isZoomed;
     }
     
     if(isZoomed == true)
     {
         GetComponent.<Camera>().fieldOfView = Mathf.Lerp(GetComponent.<Camera>().fieldOfView, zoom, Time.deltaTime * smooth);
     }
     
     else
     {
         GetComponent.<Camera>().fieldOfView = Mathf.Lerp(GetComponent.<Camera>().fieldOfView, normal, Time.deltaTime * smooth);
     }
     if(Input.GetKeyDown("g")){
         GlassesImageOn = !GlassesImageOn;
     }
     if(GlassesImageOn == true){
         GlassesImage.SetActive (true);
         dof.SetActive (false);
         GetComponent.<Camera>().fieldOfView = Mathf.Lerp(GetComponent.<Camera>().fieldOfView, glassesVision, Time.deltaTime * smooth);
     }else{
         GlassesImage.SetActive (false);
         dof.SetActive (true);
         GetComponent.<Camera>().fieldOfView = Mathf.Lerp(GetComponent.<Camera>().fieldOfView, normal, Time.deltaTime * smooth);
     }
 }
 

I get this error when i try to run it: Assets/Bino.js(14,11): BCE0018: The name 'DepthOfField' does not denote a valid type ('not found'). Did you mean 'UnityStandardAssets.ImageEffects.DepthOfField'?

When i search the forums and questions/answers and none of them suit unity 5, so i'm stuck trying to figure this out.
