ZEMAX MERIT FUNCTIONS HOW TO

To set up the Optimization Wizard as in the previous figure we use the following code: Merit functions TheMFE TheSystem. Sometimes, the ideal lens can be very thin or even overlap with other lenses due to the high negative curvature. We will use the Sequential Optimization Wizard to make a Default Merit Function target the Minimum Spot Radius also specifying the Glass/Air Boundary Values. In the Optimize tab, click on Optimization Wizard in the Automatic Optimization group This will open the Merit. To correct for this aberration, it is usually recommended to place a double achromatic lens behind the aperture stop.Р”Р„n important aspect twhen designing fisheye lenses is the mechanical aspect of the lens. Defining the Merit Function for the design. Another challenge is to reduce lateral color aberration (axial color aberration is not so much of a concern due to the short focal lengths). There is also a considerable amount of pupil aberration that needs to be corrected to reduce vignetting. Nevertheless, the design of this simple imaging system can help introduce you to the interface of ZEMAX, touch on. To do this, multiple optical elements are required, usually having negative elements at the front of the lens and positive elements at its back. Setting up a default merit function Optimizing and analyzing final design performance Introduction, Lens Prescription and Design Constraints The singlet (a single lens) is arguably the simplest imaging system modeled in ZEMAX. The algorithms are capable of optimizing a merit function composed of weighted target values these target values are called operands. One challenge of fisheye lens design is bringing all the light from these extreme angles into the sensor or viewer eye.

Once the Merit Function is complete, the optimization algorithm in ZEMAX.

ZEMAX MERIT FUNCTIONS HOW TO

Another characteristic of fisheye lenses is that the image illumination is consistent (no vignetting is present.) of /6/2012 8:55 AM ZEMAX Users Knowledge Base - How To Design a Singlet Lens.
