Image gets cut off when zooming closer

I have this model and when I zoom in, it gets cut off. I guess because it is too close to the camera.
I would like to zoom in really close. Which parameter do I have to correct?

Thanks for help

three.js docs

PerspectiveCamera( fov : Number, aspect : Number, near : Number, far : Number )

fov — Camera frustum vertical field of view.
aspect — Camera frustum aspect ratio.
near — Camera frustum near plane.
far — Camera frustum far plane.

Together these define the camera’s viewing frustum.
