Hi all,



We have an object with 13.6mm height , a convex spherical mirror with 60mm diameter and 45mm radius of curvature and a 2 feet diameter hemispherical surface (Radius of curvature 1 feet).



Here I'm attaching the optical lay out of the system. The object has to be projected onto a 2 feet hemispherical surface using a convex spherical mirror. The mirror has to be placed at a height of 270mm from the optical axis of hemispherical surface. 



How to simulate using sequential ray tracing in zemax? 



Thanks & Regards,

Kabeer

Hi Kabeer,



Are you familiar with coordinate breaks? I'd recommend taking a look at some of our resources (Getting Started Guide in-app, Help file in-app, MyZemax Knowledgebase) on the topic. Based on your drawing, you might benefit from using the Coordinate Return, but if you're not familiar with coordinate breaks in the first place, the Getting Started Guide would be a good first step. You'll find it on the Help tab of OpticStudio.



As you're building the system, remember that after each mirror surface, your thickness needs to change sign (+, -, +, - ...).
