addGap

Create an empty optical system.

opsys = opticalSystem;

To add a lens component to the optical system, create the two refractive surfaces of the lens using the addRefractiveSurface object function. Specify the lens glass material using the Material name-value argument for the first surface. Specify the center thickness of the lens, in millimeters, using the DistanceToNext name-value argument for the first surface.

addRefractiveSurface(opsys,Radius=10,DistanceToNext=4,Material=pickGlass("N-BK7"))
addRefractiveSurface(opsys,Radius=-10)

Add a gap of 3.5 millimeters between the end of the convex lens and the next component using the addGap object function.

addGap(opsys,3.5)

Add an image plane using the addImagePlane object function.

addImagePlane(opsys)

Display a 2-D visualization of the initial optical system by using the view2d object function.

hv = view2d(opsys);
