## How to place dummy surfaces at the front and rear principal planes

For a complex lens, it can be convenient to add dummy surfaces at various locations: at the entrance and exit pupils, the nodal points, or the principal planes. This article demonstrates how to insert dummy surfaces at the front and rear principal planes of a Cooke Triplet.  The surfaces will then appear in the layout plots and can be used for various analyses.

## Understanding the Detector Polar

The Detector Polar object stores the intensity data from NSC source rays that strike it. The Detector Polar is spherical in shape but the resulting data distributions in the angular domains are displayed in 2D. And this point can cause confusion.
The aim of this article is to explain clearly how OpticStudio maps rays striking 3D sphere onto a 2D intensity plot. It also gives some details on the conventions used in OpticStudio.

## Adjusting Relative Luminosity to Simulate the Visible Spectrum

Relative luminosity is very important in optical design. By defining appropriate weighting per the characteristics of the optical system, we can better model what we would expect to see. This article demonstrates a method of using wavelength weighting to model the relative luminosity of the visible spectrum as perceived by the human eye.

## Display Pupils on a Layout Plot

You can easily show the Entrance and Exit Pupils in both the LDE and Layout Plots by using dummy surfaces and pickups to show the location of the pupils without affecting the other surfaces in your sequential system.  This article walks through how to use ZPL Macro and Chief Ray Height thickness solves in the Lens Data Editor (LDE) as well as hiding dummy surfaces in a layout plot.
