Hi everybody,(adsbygoogle = window.adsbygoogle || []).push({});

I’m a new user of Zemax, I did some tutorial so I begin to know the functionalities of the soft. But my major trouble comes from the fact that I don’t know really the procedure, the drill.. to make a system from particularities data. For example, I try to do the exercises of the book “Introduction to lens design with Zemax practical example” by Joseph M. Geary. The first homework is a simple lens design from several points, and I have to calculate the mains characteristics.

Input data:

Infinity objet (20mm semi diameter)

Field : 2 incidence: 0° and 5°

Format size of the IMA : rectangular.

Aperture stop: 20 mm semi diameter (plane surface)

Thickness between Aperture Stop and first lens surface: 0

Equiconvex lens

Fnumber: f/10

Lambda: 587nm

Lens Material: BK7

Data to calculate:

EFL

Lens Power

Lens thickness

Radius of curvature R1 and R2

Format size of Ima

Airy disk diameter.

I don’t get to choose the good variables in my system, which cell must be define with marginal ray, chief ray…where start ?!?!

I hope somebody could help me.

Thank you for your replies.
